Abstract
The zero field reduced mobilities of electrons μ0 in helium, neon, argon, krypton, and xenon have been calculated as a function of gas temperatures T using the Boltzmann equation and compared with the values of the thermal electron mobilities of electrons μN obtained by Mozumder [J. Chem. Phys. 72, 6289 (1980)]. Discussion has been made about the large discrepancies between the measured and calculated values of μN in neon which were pointed out by Mozumder. The calculated exact drift velocities W in helium as a function of E/N and T have been compared with the experimental results of W for wide E/N and T ranges. A summarized figure is shown for anomalous electron mobilities in helium as a function of N at low E/N.
