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.
