In our work we apply the Basis Generator Method (BGM) [1] to the interaction between a diatomic molecule and a short laser pulse (∼ fs.). The Two Center-BGM is practical to calculate the electron dynamics with a relatively small set of functions to describe the ionization continuum. Due to the building of the basis set the coupling between the subspace A of Hilbert space, which is described in terms of our finite basis set, and its infinite complement B is minimized.
In the present work we study the ionization and molecular excitation processes in the asymmetric quasimolecule HeH2+ when it interacts with a short intense laser pulse. This system was previously studied in [2], which is a good reference to test the method.
