Mobility of Ar$^(+)$ IN Ar/C$F_4$

In this paper we present a cross section sets for Ar$^(+)$ in Ar/C$F_4$ where existing experimentally obtained data are selected and extrapolated. Monte Carlo code is applied to accurately calculate transport coefficients in hydrodynamic regime. We discuss new data for Ar$^(+)$ ions in Ar/C$F_4$ where flux and bulk values of reduced mobility are given as a function of reduced electric field E/N (E-electric field, N-gas density).
