Monte Carlo simulation of electron thermalization in gases. IV. Subexcitation electrons in hard-sphere and Maxwell model rare gases

The Monte Carlo simulation (MCS) of the thermalization of subexcitation electrons in rare gases is performed for both the hard-sphere and Maxwell model gases. The MCS result for the mass ratio m/M≲0.01 is found to be in agreement within the statistical error with the rigorous solution of the Fokker–Planck equation; therefore the upper limit value of m/M=0.01 is sufficient for the MCS to be performed within a reasonable computation time.
