Model calculations of multielectron ionization of O2 molecules by fast-heavy-ion impact.

Abstract

A simple model employing the independent-electron approximation was developed to investigate orientation effects on the cross sections for multielectron ionization of diatomic molecules in fast-heavy-ion collisions. The model was used to compare K- and L-shell ionization cross sections for ${\mathrm{O}}_{2}$ molecules with internuclear axes oriented parallel and perpendicular to the beam.
