Electron-impact ionization of Li$_{2}$

POSTER

Abstract

Electron-impact ionization cross sections are calculated for Li$_{2}$. A two active electron time-dependent close -coupling method is used to calculate cross sections for Li$_{2}$ at the equilibrium internuclear distance for incident energies of 10 eV, 15 eV, and 20 eV. The nonperturbative close-coupling cross sections are found to be lower than perturbative distorted-wave cross sections due to electron correlation effects between the two outgoing continuum electrons.
