Electron momentum distribution in scandium and the renormalized-free-atom model

The Compton profile of polycrystalline scandium has been measured using 59.54-keV ..gamma.. rays from a /sup 241/Am source. The correction for multiple scattering was calculated and its contribution was found to be approx. 0.4% at the peak of the Compton profile. Results have been interpreted by means of a renormalized-free-atom model. Good agreement between measured and computed quantities is found if the electronic configuration is chosen as 3d/sup 1/4s/sup 2/ (in atomic notation). Relativistic corrections are studied separately in an appendix. (AIP)
