Outline of Final Research Achievements

Experimental setup for investigating the intramolecular charge transfer processes in polyatomic molecules including the amino acid molecules with the pump-probe measurement using the intense attosecond pulses is developed. The method for introducing the non-volatile molecules stably in the ultrahigh vacuum chamber with the laser-induced acoustic desorption method is established. The frequency-resolved momentum imaging method in which the angular distribution of fragment ions originated from the delay-dependent signals can be securely extracted is developed. Multi-mass momentum imaging method in which the momentum images of all kinds of fragment ions can be captured simultaneously is developed.
