The complete 3D-electron momentum density (EMD) of solids can be measured by the coincident detection of an inelastically scattered hard X-ray photon and its recoil electron (i.e. a so-called () experiment). To avoid multiple scattering of the recoil electron the experiment has been performed with a 22 nm thin graphite foil made by laser plasma ablation. The experimental EMD is compared with a pseudopotential calculation. Experiments have been made both at the European Synchrotron Radiation Facility at Grenoble, France, and at the PETRA storage ring of DESY, Hamburg, Germany.
