化学反応や光応答,電子移動など分子の性質を司る最外殻軌道電子の運動を可視化することを目的として,強レーザー場における「トンネルイオン化」を利用した新規分光法の開拓を行う。気相分子を対象とし,トンネル電子の分子座標系角度分布(MFPAD)や垂直方向運動量分布(TMD)が,電子波動関数やイオン化ポテンシャルなどで決まる分子固有の観測量であることを利用する。これに円偏光レーザー場による超高速な電場の角度挿引を組み合わせることで,刻一刻と変化する分子について定量的な実時間イメージングを実現する「超高速レーザートンネル電子分光法」の基盤を構築する。

超短パルス強レーザー場におけるキラル分子のレーザートンネル電子円2色性を観測する。実験室系におけるトンネル電子の3次元運動量分布や,解離生成イオンとの相関を計測することによって,左右円偏光に対する分子応答がどのように変化するかを明らかにする。これによって,強レーザー場円2色性計測による新しいキラリティ検出法の開拓に向けた,キラル分子のトンネルイオン化ダイナミクスの理解を進める。
超短パルス強レーザー場におけるキラル分子のレーザートンネル電子円2色性を観測に向けて,実験室系におけるトンネル電子の3次元運動量分布,および解離生成イオンとの運動量相関を計測するための電子ーイオンコインシデンス運動量計測系の整備を進めた。これを用いて,D-リモネンからの光電子の計測を行い,3次元運動量分布が円偏光レーザー場におけるトンネルイオン化で予想されるトーラス形状を示すことを確認した。また円2色性の観測に向けて光学系を検討し,右回り(RCP)および左回り(LCP)のいずれの回転方向においても高い円偏光度ε>=0.97をもつ円偏光超短パルスレーザー場の発生に成功した。
<BR>
この光学系を用いて,CF4分子の解離性トンネルイオン化過程,CF4-> CF3+ + F + e-,について電子ーイオンコインシデンス計測を行った。生成イオンCF3+の運動量で定義した反跳座標系における光電子角度分布(RFPAD) は,レーザー電場がFからCに向いた場合に大きな強度をもつことが見出された。これは弱電場漸近理論(WFAT) に基づくHOMOおよびHOMO-1からのトンネルイオン化レートによる予想と定性的に一致した。一方,RFPADは偏光回転方向(RCP/LCP)に対して顕著な違いを示すことが見出され,強レーザー場における解離性イオン化においては非キラル分子も円2色性を示すことを明らかにした。
強レーザー場におけるキラル分子のトンネル電子円2色性を観測に向けて,電子ーイオンコインシデンス運動量計測系の整備が順調に進んでいる。また,強レーザー場における解離性イオン化においては非キラル分子も円2色性を示すことを明らかにするなど,分子のトンネルイオン化ダイナミクスの理解を進めることができている。
超短パルス強レーザー場にトンネル電子円2色性を観測に向けて,左右円偏光を自動切替で計測するための制御系の構築を進める。分子ビーム源の設計・製作と合わせて,精密な円2色性の計測を実現しキラル分子の分子応答を明らかにする。これによって,強レーザー場円2色性計測による新しいキラリティ検出法の開拓に向けた,キラル分子のトンネルイオン化ダイナミクスの理解を進める。

To understand tunneling ionization of molecules, an electron-ion coincidence measurement system using a high-repetition rate laser was constructed. It was shown that the characteristics of the highest-occupied molecular orbital (HOMO) of hydrogen molecule can be read out from the three-dimensional torus-like structure of tunneling electrons in the molecular frame. On the other hand, the application to tetrafluoromethane revealed that the recoil-frame angular distribution has a dependence of the helicity of the circularly polarized laser fields, due to the correlation between ionization and dissociation. A new method utilizing an auxiliary dissociation pulse was developed to disentangle the correlation, and applied successfully to oxygen molecule. In addition, adiabatic theory for diatomic molecules incorporating the molecular vibration was developed.

We studied laser tunneling ionization of molecules in ultrashort intense laser fields to develop an electron dynamics imaging technique. Two observables of tunneling ionization, (1) ionization rates and (2) electron transversal momentum distributions (TMDs), were measured to compare with predictions by tunneling ionization theories. It was demonstrated that one can (1) read out the asymmetric 2π highest occupied molecular orbital (HOMO) of nitric oxide by using shaped intense laser pulses and (2) obtain the TMDs of deuterium molecule from the cross sections of a photoelectron torus in the molecular frame.

In this research, we aimed to observe the electron emission process of atoms by using free electron laser SACLA of RIKEN, combined use of free electron laser (FEL) and near infrared (NIR) femtosecond laser. Using X-ray beamline BL 3 at SACLA, side-band formation by NIR laser was observed in the Auger electron spectra of rare gases. The sideband intensity enables us to optimize the spatial and temporal overlap by of the two lasers. In addition, a highly-excited states of single-charged xenon was probed by using NIR laser in combination with soft X-ray beamline BL1, and their decay was probed in real time.

Many-body chemical reaction processes induced by intense laser fields are studied by using laser filament formed by femtosecond laser pulses focused by a long focusing length lens. Intense laser pulse (~40 fs, ~1mJ/pulse) were focussed to a gas-cell containing ethylene gas (~1 atm) to form a laser filament. The produced materials were analyzed by using TEM, EELS and XPS etc to show that the main products are hydrogenated amorphous carbons. It was found that the sp2/sp3 carbon ratio and the size of the nano-particles varies sensitively depending on the wavelength and intensity of the laser fields.

We investigated the multielectron dynamics of molecules such as CO and N2 in intense laser fields by using electronic and nuclear wavepacket propagation methods and proposed laser control schemes of the generation of higher order harmonics which is a source of attosecond pulses. We experimentally demonstrated that the two C-O bonds of CO2 can be asymmetrically cleaved by changing the phase between two-color pulses, which provides a new possibility of the laser control of chemical reactions. We also established a method to simulate XFEL-induced Coulomb explosion of molecules for time-resolved molecular imaging.The results of application to iodouracil etc. are in good agreement with the experimental results.

A system for ultrafast photoelectron spectroscopy was constructed using laser high-order harmonics in extreme ultraviolet, which was successfully applied to femtosecond pump-probe real-time tracking of ultrafast electron wavepacket dynamics. The effect of electronic excitation in molecular dynamics in intense laser fields was studied by momentum imaging of dissociative ionization of UV-excited molecules. Based on the finding, a novel method to visualize electron dynamics in molecules in real time was proposed. Photoelectron spectroscopy of molecules before and after the irradiation of an intense laser pulse was performed, revealing selective excitation of specific electronic states in the laser field.

Multi-photon absorption processes of atoms in intense short-wavelength laser fields has been studied by photoelectron spectroscopy. We have applied the magnetic bottle electron spectroscopic method, to achieve effective photoelectron spectroscopic researches with light sources of ultra intense and high photon energy. We have studied the three-photon double ionization of Ar in intense extreme ultraviolet free-electron laser fields over a photon energy range of 19.6-22.0 eV. It is found that the double ionization to Ar2+ proceeds sequentially via the formation of singly charged Ar+ states and is enhanced around photon energies of 20.5 and 21.5 eV. Two types of resonances are identified in the two-photon ionization of the Ar+ states: (i) resonances to intermediate states at the one-photon energy level and (ii) those to autoionizing states above the Ar2+ ionization threshold.

強光子場における分子ダイナミクスのレーザー偏光方向に対する分子配向依存性を明らかにするために,12fs程度のパルス幅を持つ極短パルス強光子場中(〜10^<14>W/cm^2)におけるH_2Sのクーロン爆発過程をコインシデンス運動量画像法を用いて調べた。フェムト秒チタンサファイアレーザーシステムから出力された光パルス(波長800nm,パルス幅<40fs,繰り返し1kHz)の一部を,Arガス(〜0.1MPa)を充填したセル内に設置された中空ファイバーに導入しスペクトルの広帯域化を行った後、チャープミラーにより分散補償を行いパルス圧縮した。フリンジ分解自己相関波形から求められたパルス幅は9.0fsであり,パルスあたりのエネルギーとして0.4mJを得た。分子平面の方向はその法線ベクトル(n)を3体クーロン爆発過程によって観測されたH^+の運動量外積として定義し,クーロン爆発事象毎に決定した。光子場強度3×10^<11>W/cm^2における3体クーロン爆発過程,H_2S^<3+>→H^++S^++H^+,によって生成したH^+の運動量相関図には,p_1(=p_2)=37×10^3amu m/s及び45×10^3amu m/sに2つのピークが観測された。これら2つの成分はレーザー偏光ベクトル(ε)と分子平面が平行な場合(ε⊥n)および垂直な場合(ε//n)にそれぞれ観測され,異なる分子配向による分子ダイナミクスの違いを反映している事が明らかになった。測定された運動量からクーロン爆発直前のH-S結合距離R(H-S)は,ε⊥nの場合R(H-S)=2.6Å,ε//nの場合R(H-S)=1.9Åと見積もられた。このことは,分子平面が偏光ベクトルに対して平行な場合にH_2Sがより伸張した構造を持つことを示している。

本研究では,クーロン爆発によって生成した多価原子イオンと電離電子の運動量分布を同時計測し,イオンおよび電子の持つ運動量ベクトルの相関にもとづいて強光子場中分子ダイナミクスを明らかにすることを目的とする.本年度はこの目的のために開発したコインシデンス運動量画像測定システムを用いて,強光子場中分子から生成したイオンおよび電子の運動量画像計測を行った。光子場強度(0.15PW/cm^2,70fs)におけるアセトニトリルの2体クーロン爆発過程には,3つの異なる経路CH_3CN^<2+>→CH_<3-n>^++H_nCN^+(n=0,1,2),すなわちC-C結合が直接解離する経路(n=0)に加えてメチル基(-CH_3)からニトリル基(-CN)への水素移動を伴う経路(n=1,2)が存在することが明らかとなった。これらの経路に対する分岐比がほぼ等しいことから,水素移動反応がクーロン爆発と競合して極めて高速に進行することがわかった。また,レーザー偏光方向に対する生成フラグメントイオンの空間異方性の解析から,メチル基からニトリル基への水素移動が進むにつれて,親イオンCH_3CN^<2+>の寿命が長くなることを見いだした。
さらに,コインシデンス画像法とポンプ-プローブ計測を組み合わせて強光子場において生成したCS_2^<2+>のダイナミクスを実時間追跡した。運動量相関図には,ポンプ-プローブ遅延時間に対して鋭敏に変化する2つの異なる成分が見いだされた。これらはそれぞれCS_2^<2+>のポテンシャル曲面上で反対称伸縮振動および対称伸縮振動方向へ移動する核波束に対応し,その収量から対称伸縮振動方向の運動に伴って2つのC-S結合が同時に解裂する過程が,強光子場において極めて効率よくおこることが示された。
また,強光子場中CS_2から生成した光電子の画像観測を行い,基本波と2次高調波を混合した光子場において,光電子空間分布が位相に応じて鋭敏に変化することを見いだした。

1.強光子場中炭化水素分子の超高速水素ダイナミクス
強光子場中(〜10^<14>W/cm^2)において、メタノール分子からの水素分子イオン(H_2^+,H_3^+)生成を質量選別運動量画像法により明らかとした。フラグメントイオンの収量比と運動量ベクトル分布の異方性から、水素分子イオンの生成速度を明らかとした。また、コインシデンス運動量画像法を用いて強光子場中メタノール分子の2体クーロン爆発過程を調べ、フラグメントの角度分布の異方性から、前駆体CH_3OH^<2+>の寿命が、H^+放出の場合が70-290fs、H_2^+放出の場合が110-550fs、H_3^+放出の場合が1.4psよりも長いことが明らかとなった。さらに、H/D移動もしくはH/D交換を伴うC-O結合解離過程が確認され、フラグメントイオンの異方性および収量比より、水素移動が強レーザーのパルス時間幅の間に起こることが明らかとなった。
2.軟X線強光子場におけるH_2,D_2の解離性越閾イオン化
軟X線強光子場(〜3×10^<12>W/cm^2)におけるH_2およびD_2分子の解離性イオン化過程を調べた。高調波強度に対して、H_2より生成したH^+の生成量が1.7(1)次、D_2より生成したD^+の生成量が1.6(2)次の非線形依存性を示すことが明らかとなった。H^+とD^+の運動エネルギー分布およびその生成量の非線形性が、2つの協奏するイオン化過程、(i)1光子解離性イオン化と(ii)解離性2pπ_u状態への2光子吸収1価イオン化(ATI)によって解釈できることを示した。

The three-body Coulomb explosion process of CS_2 in intense laser fields (〜 60 fs, 0.36x10^<15> W/cm^2), CS_2^<3+> → S^+ + C+ + S^+, is studied by the triple coincidence momentum imaging of the atomic fragment ions. The set of the observed momentum vectors of the fragment ions determined for respective explosion events exhibits a dear trajectory originating from the rotational motion of an intermediate CS^<2+> ion, formed in a sequential explosion process of CS_2^<3+> prior to the complete three-body fragmentation. The analysis based on the classical free-rotor model shows that the metastable CS2+ ion has a sufficiently longer lifetime than its rotational period (〜20ps). The molecular structure of CS_2^<3+> just before the Coulomb explosion is reconstructed from the average momentum values of the S^+ and C^+ ions produced through the concerted three-body Coulomb explosion pathways under the assumption that the potential between the fragments is Coulombic. The mean C-S bond length of <r> =2.5A and the azimuthally averaged S-C-S bond angle, <γ> = 145° thus determined indicate that structural deformation occurs to a large extent in the intense laser fields.

In order to clarify the role of light-dressed states in the dynamics of a multielectron molecule in intense laser fields, the dissociation processes, O_2^+→O^++O, in intense laser fields (100fs, 〜3×10^<14> W/cm^2) are studied at the laser wavelength of 795 nm and 398 nm on the basis of the momentum imaging maps of the O^+ fragment ions. The covariance map measurements are performed with high momentum resolution to assign securely the dissociation pathways. From the anisotropic momentum distribution of O^+ with respect to the laser polarization direction, the electronic states of O_2^+ are found to be coupled exclusively through parallel transitions in the course of the dissociation process. The released kinetic-energy of O^+ for both 795 nm and 398 nm are interpreted consistently by a sequential coupling model of light-dressed potential curves of O_2^+ in the quartet Π- state manifold.
The dispersed fluorescence spectra of NO and O_2 were measured in the spectral range between 300 nm and 700 nm using a spectrometer equipped with a intensified CCD camera. The observed spectra exhibits a number of spectral lines, most of which were assigned to the electronic transition of the higher charged fragment ions, such as N^+, N^<2+>, O^+ and O^<2+>. A high-resolution (〜2 cm^<-1> ) measurement was performed for the N III 3^2P°→3^2S transition at 409.24 nm. The observed spectra show a doublet pattern when the laser polarization is directed towards the spectrometer, which is interpreted as a result of a large released kinetic energy imposed on the N^<2+> fragment ion through the Coulomb explosion of NO.Based on the kinetic energy estimated from the split pattern of the spectra, it was found that the N^<2+> fragment was produced through the Coulomb explosion process, NO^<4+>→N^<2+>+O^<2+>.

超音速ジェット中に生成した、水銀・ネオン2原子クラスター(HgNe)をレーザー2色2光子共鳴法によってイオン化し、イオン化スペクトルの測定を行った。リフレクトロン型飛行時間質量分析器を用いることによって、生成したイオン種を高質量分解能で検出し、単一質量イオン種についてのイオン化スペクトルを得ることができた。測定されたスペクトルには、HgNeのイオン化限界付近(83880-84020cm^<-1>)で振動自動イオン化によるシャープな構造が見いだされた。低エネルギー分解能測定(δν=0.7cm^<-1>)によって観測された主なピークは、フランクコンドン的に明るい、イオンコアの振動量子数がv^+=2,3のイオン化限界に収斂するd-リュードベリ系列に帰属された。さらにレーザーキャビティ内エタロンを用いた高エネルギー分解能測定(δν=0.05cm^<-1>)によって、それぞれのピークは複雑な共鳴構造を持つことが見いだされた。例えば、v^+=2リュードベリ系列の一つのピークは、フランクコンドン的に暗く、より準位密度の高いv^+=1リュードベリ系列との結合によっていくつかの小ピークにわかれる。イオン化スペクトルにおけるこのような階層構造は、光励起によって生成したv^+=2イオンコアを持つリュードベリ状態が、電子とイオンコアの衝突によるエネルギーの授受によって、v^+=1のリュードベリ状態に遷移し、最終的にv^+=0のイオンを生成する過程の存在を示唆している。半古典的に考えた場合、電子とイオンコアのエネルギーの授受は。衝突の際のイオンコアの振動の位相に依存するので、イオン化過程がストカスティックなものとなることが予想されている。多チャンネル量子欠損理論を用いたより詳細なスペクトルの解析によって、量子系におけるカオスのふるまいを探ることができると考えられる。
