dc.description.abstractWe report results for the single- and multi-photon ionization of the H2 + ion irradiated by ultrashort elliptically polarized laser pulses with central photon energies from the ionization threshold up to 300 eV. Using the fixed-nuclei approximation, the electronic response of the system is calculated through an ab initio time-dependent grid-based approach implemented in two-center prolate spheroidal coordinates. Cross sections for single-photon absorption are analyzed by means of a time-independent picture. We show that a concise decomposition of the cross-section pattern exists in terms of the linear and circular portions of the generally elliptical polarization. An asymmetric rotational effect in the angular distribution of the ejected electron is predicted and discussed according to the above decomposition. Furthermore, the dependence of the angular distributions on the pulse length is analyzed in detail.en_US
