Abstract
In a typical Compton experiment with photons the inelastic scattering cross section for x or γ rays is recorded at a fixed scattering angle almost in the backscattering direction [1]. The information on the electrons of the scatterer is imbedded in the Compton line shape, i.e. the Compton profile (CP). For electrons with ionization energies much less than the energy transfer from the photons, the impulse approximation [2] relates the CP to the ground state momentum distribution of the scattering electron system. Compton spectroscopy thus offers a direct possibility to probe the ground state of molecules and solids.
