Clocking ultrafast wave packet dynamics in H2 by using UV pump - UV probe schemes

Abstract

We theoretically investigate the use of UV pump - UV probe schemes with two identical pulses to excite and ionize the hydrogen molecule. The nuclear wave packet (NWP) generated in excited states of neutral molecules is traced by analyzing the asymmetry of the electron angular distributions resulting from dissociative ionization. The mapped NWP can be later used to selectively launch the ionization process into different channels. © Published under licence by IOP Publishing Ltd.
