The collision cross-sections for proton-argon interaction based on ab initio ArH+ potential

摘要

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 HC Ar system are evaluated at the kinetic temperature T 2 T100; 10 000 U.K/ by means of the asymptotically correct analytical potential constructed for the ground X1 C state of the ArHC 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.
