Abstract: Integral and differential elastic collision cross-sections for Ar+ ions with neutral Ar atoms are calculated using modified Tang and Toennies ion-atom interaction potential models, TTIA and TTIA-wb, to describe experimental spectroscopic data for the Ar2+ molecular ion, and the phase shifts are calculated by the JWKB approximation. Results are presented for center-of-mass energies in the 1 meV to 10 eV range. In our calculations, the effects of the spin-orbit interaction are included through a semi-empirical model. The results obtained agree with the scarce data available in the scientific literature.
