Abstract
The authors report coincidence measurements between inelastically scattered 148 keV photons and the recoil electrons generated within an 80 nm thin Cu foil. They have analysed the Doppler broadening of the scattered photon intensity, which corresponds to a scan through the three-dimensional electron momentum density (EMD) parallel to the momentum transfer vector. The experimental data are compared with a theoretical EMD from the modified augmented plane wave method. A Monte Carlo calculation is described that allows for the correction of multiple electron scattering within the foil. Estimates of the triple-differential cross section for Compton scattering are given. The experiment was performed with the synchrotron radiation from a bending magnet of the DORIS storage ring at Deutsches Elektronen-Synchrotron (DESY), Hamburg, Federal Republic of Germany.
