Revised Born-Oppenheimer approach and a multielectron reprojection method for inelastic collisions

Chemical Physics 2015-05-20 v1

Abstract

The quantum reprojection method within the standard adiabatic Born-Oppenheimer approach is derived for multielectron collision systems. The method takes nonvanishing asymptotic nonadiabatic couplings into account and distinguishes asymptotic currents in molecular state and in atomic state channels, leading to physically consistent and reliable results. The method is demonstrated for the example of low-energy inelastic Li+Na collisions, for which the conventional application of the standard adiabatic Born-Oppenheimer approach fails and leads to paradoxes such as infinite inelastic cross sections.
