Electron Mobility for Arbitrary Cross Section. Research Status Report No. 79-0001 for the Period February-May 1979

摘要

Approximating the electron-atom elastic collision cross section as a piecewise linear function of electron speed, one is able to express analytically the electron mobility as a function of density, temperature and cross section. Results are given for a two term expansion in Sonine polynomials of the speed dependent functions of the classical expansion of the electron velocity distribution function. The method is particularly appropriate for determining the sensitivity of mobility to cross section and the variation of mobility with atomic species. (ERA citation 05:016990)
