ENERGY DISTRIBUTION OF ELECTRONS EJECTED FROM TUNGSTEN BY HE PLUS

The results of a calculation of the energy distribution of electrons ejected from tungsten by low energy He are presented. The calculation is based on a mechanistic model of the process in which the ejected electrons are divided into two groups 1 the electron excited in the primary process t at can escape directly and, 2 the electrons that escape because of interactions between the primary electrons and those of the band structure of the solid. cond ry electron data are used to predict the portion resulting from this second mechanism.
