Abstract
The inelastic scattering cross section from the tightly bound 1s electrons at the intermediate momentum transfer from Cu and Zr was measured using a 59.54-keV γ-ray source and a coincidence technique. A good statistical accuracy was achieved by using a NaI-scintillation counter for the fluorescence detection. The experimental results are compared with the impulse approximation which seems to explain the spectral shape surprisingly well. Neither the Compton peak shift nor any predicted structure in the measured spectra is observed.
