We give experimental spectra for 70-and 62-keV x rays inelastically scattered from the A^-shell electrons of copper. The x rays scattered from the K shell were selected by fluorescence coincidence. The scattering is in a momentum-transfer regime in which the impulse approximation is not valid, and atomic binding effects are important. The data are in agreement within experimental uncertainties in absolute scattering strength and spectra shape with a Hartree-Fock-Slater calculation. In contrast to previous work we do not see separate spectral features attributable to Compton and Raman scattering.PACS numbers: 32.80.Cy, 32.80.Hd At high momentum transfers inelastic x-ray scattering is well described by the impulse approximation x in which the spectrum of scattered x rays is determined by the momentum distribution of the electronic initial state. The aim of this work was to examine the x-ray scattering process beyond the impulse-approximation regime by inelastically scattering x-rays from deeply bound A'-shell electrons of orbital radius a at intermediate momentum transfers (qo^\/a). 2 In this momentum-transfer regime, unlike the limit qoa^>\, the electron is excited to a state which is not well described as a free-electron plane wave. Furthermore, we are sensitive to electricdipole-forbidden transitions, which are not revealed in x-ray photoabsorption spectroscopy (which is spectroscopically equivalent to the limit qa
