Electron Scattering from Copper

Abstract

A measurement of the total cross section for the excitation of the 42p state in copper by 60 eV electrons is described. These relative measurements are converted into absolute values by a generalised oscillator strength formalism which is also described. The result agrees very favourably with that predicted by a four state close coupling calculation, but is about a factor of three smaller than the previous measurement of Trajmar et al. (1977).
