“…Figure 6 depicts the drift velocities (Robson et al, 2005;Ness & Robson, 1986;Nikitović et al, 2018;Nikitović & Raspopović, 2021) obtained by simula-tions using the Monte Carlo method in both real space (bulk) and velocity space (flux). Bulk values are computed as the center of mass displacement over time, ∆z c.m /∆t, while flux values correspond to the mean velocity of ions, < v >.…”

In this work, we present a complete cross sections set that describe the interaction between H + 2 ions and H2 molecules. Based on these cross sections, we have calculated the transport properties of H + 2 ions in H2 gas, depending on the reduced electric field. Ionic charge exchange 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 in hydrodynamic regime. We discuss new data for H + 2 ions in H2 gas where the mean energy the flux and bulk values of reduced mobility and other transport coefficients, are given as a function of low and moderate reduced electric fields.

“…The transport parameters of He + ions swarm in neutral gases He and CF 4 , as well as in mixtures were calculated: (1) 5% He + 95% CF 4 (2) 30% He + 70% CF 4 and (3) 70% He + 30% CF 4 . The flux and bulk drift velocities (Robson et al, 2005;Ness & Robson, 1986;Nikitović et al, 2018;Nikitović & Raspopović, 2021) for He + in He/CF 4 mixtures as a function of E/N are given in Figure 3. The drift velocities obtained by the Monte Carlo simulation are calculated in real space (bulk) and in velocity space (flux) values which are obtained as d < x > /dt and < v >, respectively.…”

A complete set of cross sections for helium ions in a mixture of helium and carbon tetrafluoride is recommended. The transport properties for He + ions in He/CF4 mixtures required to model the discharge containing the mentioned ions were calculated by the Monte Carlo method at a temperature of T = 300 K. In this paper we give the drift velocity, characteristic energy, reduced mobility and specially rate coefficients for low and moderately reduced electric fields E /N (E-electric field, N-gas density) and accounting for nonconservative collisions. This paper is dedicated to the presentation of the set for He + ions scattering cross-sections in CF4 which is estimated using available experimental data for exothermic charge transfer cross-sections producing CF + 3 and CF + 2 ions and endothermic charge transfer cross-section producing CF + , C + and F + ions. The aim of this paper is to determine how the addition of a percentage for He in He/CF4 mixtures affects the separation of bulk and flux transport parameters for He + ions.
