Title: Computer simulation study of correspondence between experimental and theoretical electron drift velocities. II. Constant total collision frequency model gases
Abstract: Electron drift velocities WSC and WFD obtained respectively from Schlumbohm's and Frommhold's experiments are calculated by a Monte Carlo simulation for five cases of model gases. The obtained drift velocities are compared with the theoretical drift velocities defined as the average velocity Vd of the steady state Townsend condition and the average velocity Wv, the centre of mass drift velocity Wr and the mean arrival time drift velocity Wm of an isolated electron swarm, which are calculated by a separate Monte Carlo simulation in a free space for the respective model gases. It is found that WSC is almost equal to Wm, and that WFD is almost equal to drift velocity Ww represented as 1/2 (Wr+Wm), for the E/N values studied here. It is also found that the difference between electron drift velocities depends not only on the E/N value but also on the value of the effective ionization frequency.
