Abstract
The ionization dynamics of H2
+ exposed to high-intensity, high-frequency, ultrashort laser pulses is investigated
with two theoretical approaches. The time-dependent Schrödinger equation is solved by a direct numerical
method, and a simple two-center interference-diffraction model is studied. The energy and angular
distributions of the photoelectron for various internuclear distances and relative orientations between the
internuclear axis of the molecule and the polarization of the field are calculated. The main features of the
photoelectron spectrum pattern are described well by the interference-diffraction model, and excellent quantitative
agreement between the two methods is found. The effect of quantal vibration on the photoelectron
spectrum is also calculated. We find that vibrational average produces some broadening of the main features,
but that the patterns remain clearly distinguishable.
