Abstract : Classical differential cross sections for scattering of a free electron by a bound electron are used to calculate the electron slowing down spectrum for cases in which experimental results are available for comparison. The calculations are found to be in good agreement with measurements in aluminum, copper and gold from 300 eV to 20 keV when a single, average, empirically determined binding energy is used. The agreement is not as good when the electronic structure of these metals is included in a more realistic way. Two different approximations to the classical cross section are used, and the one which presumably accounts more completely for the electron binding gives the poorer results. (Author)
