Laser-induced ionization of diatomic molecules studied by an extension of the Basis Generator Method — •Luis F. Menchero and Tom Kirchner — Institüt für Theoretische Physik, TU-Clausthal. Leibnizstraße 10. D-37678 Clausthal-Zellerfeld. Germany.
In this work we extend the Basis Generator Method (BGM), described by Lüdde et al J. Phys. B.: At. Mol. Opt. Phys. 29, 4423 (1996) to the interaction between a diatomic molecule and a laser pulse. The obtained Extended Two Center (XTC-) BGM is practical to calculate the ionization probabilities with a relatively small set of functions, since the included basis states are constructed such as to minimize couplings to that part of Hilbert space which is not spanned.
Our aim ist twofold: Firstly, we have checked the validity of the XTC-BGM by applying it to the one-electron (HeH)2+ quasimolecule in a short, strong field. Secondly, the approach can be easily generalized to many-electron molecules within a single-active electron model. First results will be presented at the conference.
