Abstract
We have used a coincidence technique to measure the inelastic x ray scattering spectrum from copper K-shell electrons at an incident energy of 70 keV. We cover a range of momentum transfers h/2πq over which 0.5 ≤ qa ≤ 1.1, where a is the Bohr radius of the copper K-shell. This is a momentum transfer regime in which the impulse approximation is no longer valid. The data presented are compared to the results of a one-electron calculation and agree well in both spectral shape and absolute cross section. In contrast with previous work of this type we do not see separate spectral features attributable to Raman and Compton scattering.
