Abstract
Recommended values are presented for qm, qt and QT (momentum transfer cross-sections for elastic collisions, total cross-sections for elastic collisions and total collision cross-sections, respectively) of electrons in xenon for electron energies from 0 to 104 eV. Recommended values of ionisation cross-sections qi are also presented. Using these values of qm together with values of qi and Townsend ionisation coefficients alpha , recommended values of total excitation cross-sections qe are determined. The values of qm for electron energies from 5 to 20 eV are smaller than those of Frost and Phelps (1964) by a considerable amount. The values of qe for energies from about 20 to 100 eV are much larger than those of de Heer et al. (1979).
