Abstract : The contribution to the secondary electron energy spectrum, f(E), produced by primary electron beam excitation of the core levels has been determined using a continuous binding energy distribution for the bound electrons deduced from the Thomas-Fermi atomic model. As such, the parameters of the distribution are only Z, the atomic number, and the primary electron energy, (E sub p). For large (E sub p), the contribution to the secondary electron spectrum from the core levels becomes increasingly dominant as compared to that from the conduction band as E increases. Numerical results are presented which also includes evaluation of the distribution of energy loss into secondary kinetic energy and recombination. (Author)
