Abstract
For pt.I see ibid., vol.11, p.325 (1978). Theoretical values for the electron drift velocity have been calculated in mercury, sodium and thallium for 7*10-18-16 V cm2 using Boltzmann's equation. The momentum cross-section for electron/atom collisions has been obtained as a function of electron energy by using an iterative procedure which produces a good agreement between the calculated and experimental values of the drift velocity. Other electron swarm parameters have been calculated as a function of E/N: namely, electron mean energy, the ratio of radial diffusion coefficient to mobility and the fraction of swarm energy loss to inelastic collisions.
