Abstract
Theoretical total cross-section results for all ionization and capture processes in the ${\mathrm{He}}^{+}$-He collision system are presented in the approximate impact energy range of 10--1000 keV/amu. Calculations were performed within the framework of time-dependent spin-density functional theory. The Krieger-Li-Iafrate approximation was used to determine an accurate exchange-correlation potential in the exchange-only limit. The results of two models, one where electron translation factors in the orbitals used to calculate the potential are ignored and another where partial electron translation factors are included, are compared with available experimental data as well as a selection of previous theoretical calculations.
