Abstract
Semi-empirical total cross sections for electron scattering of noble gases (Ne, Ar and Kr) in the energy range 0.5-10 keV have been obtained by combin ing transmission-beam measurements for impact energies up to 6 keV with an asymptotic behaviour at higher energies according to the Born-Bethe approxi mation. The influence of the forward electron scattering on the experimenta l system has been evaluated by means of a Monte Carlo electron transport si mulation. Theoretical values have also been obtained by applying the Born a pproximation in the case of inelastic processes and by means of an atomic s cattering potential for the elastic part. The results of these calculations show an excellent agreement with the semi-empirical values in the above-me ntioned energy range.
