The collision cross-sections for proton-argon interaction based on ab initioArH+ potential
Abstract
The classical collision cross-sections of a proton with an argon atom as well as the thermal transport coefficients and rate constant of the colliding H+-Ar system are evaluated at the kinetic temperature T\in [100,10 000]~(K) by means of the asymptotically correct analytical potential constructed for the ground X1Σ+ state of the ArH+ cation from the highly accurate ab initio data available in the entire range of internuclear distances (Terashkevich et al., J. Quant. Spectrosc. Radiat. Transfer, vol. 234, 2019, pp. 139-146). The results can be useful to estimate thermodynamic, transport and kinetic properties of the Ar/H2 plasma in a wide temperature range.
