Influence of the Ramsauer-Townsend minimum on the electron energy distribution function and electron transport in xenon

摘要

The electron distribution function in xenon in the low-energy region comprising the Ramsauer-Townsend minimum was obtained by solving the Boltzmann equation in the hydrodynamic approximation. for electric field to gas density ratios E/N in the. range (0.01 3) Td. The distortion of the electron distribution function due to the minimum is analysed and correlated to the behaviour of the electron transport coefficients: the drift velocity W-d and the ratio of the transverse and lonaitudinal diffusion coefficient to mobility,. D-T/mu and D-L/mu. The results are discussed in view of the different theoretical and experimental cross-section data used.
