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. I...
Results are presented for the calculated drift velocities and diffusion coefficients for Ar+ ions in helium at atmospheric pressure, temperature T=300 K and for reduced electric fields E/N from about 1 Td up to about 150 Td, using Monte Carlo techniques. The drift velocities range from 5.94×103 to 559.0×103 cm s-1 for the Ar+ ions in the ground state 2P3/2 and from 5.85×103 to 545.0×103 cm s-1 for the Ar+ ions ...
