| Research Abstract |
Photochemical reaction induced by intense laser fields opens a number of channels producing a variety of electronic, vibrational, and rotational states. In this study we aimed to reveal "the ionization dynamics via excitation of neutral molecules" and "the correlation between photoemission and dissociation channels". The following five achievements have been obtained. (1) Time-resolved observation and simulation of rotational wave packet of nitrogen molecules, (2) Identification of ionization and excitation pathways of ethanol in intense laser fields using photoelectron-photoion coincidence imaging, (3) Intensity dependence of photoelectron angular distribution for multichannel ionization of Kr, (4) Development of an experimental method for measuring photoelectron interference, (5) Formulation of ultrafast multichannel photoionization theory and numerical simulation of ionization of Ar.
