Comparison between Transport Properties for H2+ in H2 and H2+ in Ar Gas

Abstract

In this work we present a cross-sections dataset and transport properties of H2+ in H2 gas and H2+ ions in Ar gas. The ionic charge transfer reactions with molecules are indispensable elementary processes in the modeling of kinetics in terrestrial, industrial, and astrophysical plasma in the detection of dark matter. A Monte Carlo simulation method is applied to accurately calculate transport parameters for the hydrodynamic regime. We discuss new data for H2+ in H2 gas and H2+ ions in Ar gas where the drift velocity, characteristic energy, flux and bulk values of reduced mobility and diffusion coefficients are given as a function of low and moderate reduced electric fields, E/N (E-electric field strength, N-gas density).
