Electron momentum spectroscopy measurements of graphite single‐crystals are presented. Data were taken for incoming electrons with an energy of 50 keV, and both outgoing electrons with an energy near 25 keV. Spectra are presented for the major symmetry directions of graphite. To remove the effect of inelastic multiple scattering we use in all cases an identical deconvolution procedure, which consistently removed all intensity at high energy loss values. However the intensity becomes vanishing small only for binding energies of about twice the bandwidth. The shape of the observed spectra compare well with many‐body calculations based on the cumulant expansion scheme but the intensity at high momentum is less than predicted by this theory. © 2003 American Institute of Physics
