An approximate method for calculating drift velocity and other kinetic coefficients of heavy ions
in a light gas is generalized to gaseous mixtures. Obtained equations are used to calculate the mobilities of
and ions, as well as rate constants for inelastic ion–molecule processes with these ions in helium with
small additions of O2 under an electric field. Calculated ...

The Smirnov method for obtaining the drift velocity of heavy ions in a light gas is generalized to
calculate the rate coefficients of threshold ion–molecule reactions. Different versions of this simple
method are used to calculate the mobility and rate coefficients for O4−,O2−, and NO− ions moving
through helium under the influence of an electric field. Calculated results ...

Using an approximate approach that is valid for a large ratio of the ion mass to the mass of the neutral
particle, the mobility of O2+, N2+, O2-, and O4- ions was calculated in helium and good agreement was
obtained with the available results of Monte Carlo calculations and experimental data at high values of the
reduced electric ...

The kinetics of electrons and negative ions was numerically studied under the conditions, which are typical for multi-pulsed guided ionization waves in He flows ejected into ambient air. It was shown that, in He with a small admixture of O2 or air, O2- ions formed due to three-body electron attachment in the discharge afterglow are rapidly ...

The population annealing method is a promising approach for large-scale simulations because it is potentially scalable on any parallel architecture. We present an implementation of the algorithm on a hybrid program architecture combining CUDA and MPI. The problem is to keep all general-purpose graphics processing unit devices as busy as possible by efficiently redistributing replicas. ...
