A package for the ab-initio calculation of one- and two-photon cross sections of two-electron atoms, using a CI B-splines method
Description
Abstract A package is presented for the fully ab-initio calculation of one- and two-photon ionization cross sections for two-electron atomic systems (H^- , He, Mg, Ca,...) under strong laser fields, within lowest-order perturbation theory (LOPT) and in the dipole approximation. The atomic structure is obtained through configuration interaction (CI) of antisymmetrized two-electron states expanded in a B-spline finite basis. The formulation of the theory and the relevant codes presented here represent t...
