Abstract: Experimental and theoretical investigation of single-electron capture and additional experimental studies of single-electron loss cross sections in He+-Ar collisions at impact energies of 1.5-5.0 keV for experimental studies and from 10 to 4000 keV for the theoretical calculations are presented. Comparisons are made with other experimental results, for single-electron capture the present measurements confirm the behaviour observed by previous measurements in the energy range 1.5-5.0 keV, except with the data of Eisele and Nagy (1977 J. Chem. Phys. 66 883-5), and for single-electron loss an extrapolation of the high-energy results to low energies shows good agreement with the present data, giving the general shape of the cross section curve. Our theoretical calculations are in good agreement with the experimental data and reproduce the main features of the cross section energy dependence. We present the most important contributions to the total cross sections from the partial capture cross section to the He(1s) and He(n = 2) states, with the former as the dominant channel over the energy region considered.
