| Outline of Final Research Achievements |
Using direct simulation of the time-dependent Schrodinger equation, we have studied the progress of photoionization and the interplay between different ionization paths. Upon inner-shell ionization, “Attosecond knock-up”, where the outgoing continuum electron collides with the remaining outer electron, depends on pulse polarization. Upon near-threshold EUV+IR two-photon ionization, the competition between resonant and nonresonant paths leads to striking pulse-delay dependence of photoelectron angular distribution. Thus, out study has revealed various possibilities to control photoionization processes.
