Abstract : Classical differential cross sections for electron-electron scattering are used to calculate the electron slowing down spectrum. The important feature of these cross sections is their inclusion of the motion of the bound electrons, which is an essential part of allowing for the binding. Some general aspects of the solution of the energy degradation equation are discussed, and numerical results are presented for some idealized problems. These results illustrate many features of the electron cascade that develops as fast electrons slow down. The results obtained by including the motion of the bound electrons are also compared with those which consider the bound electrons stationary. It is found that allowance for the motion of the bound electrons increases the flux at low energy. (Author)
