Abstract
The Compton profile of single crystal chromium has been measured for the [100] and [111] directions with AgKα X-rays and found to be narrower than the profile calculated for the free atom. This is consistent with the X-ray scattering factor observations of Diana and Mazzone and suggests that the 3d electrons in the metal are spatially more extended than in the free atom. Approximate metallic wave functions are given for chromium which are consistent with the scattering factor and Compton profile observations including the observed anisotropics in both.
The momentum distributions of the 3d metals Ti, V, Cr and Fe all show rapid changes of values of momenta, and hence of kinetic energy, significantly larger than those predicted by free electron theory, as might be expected for 3d valence electrons.
