Abstract
Directional Compton profiles for magnesium single crystals are measured using 60 keV γ rays, and are compared with the theoretical profiles calculated by the APW method. Good agreement is found between the experimental and the theoretical Compton profiles. However, the conduction electron part of the experimental Compton profile is slightly broader than that of the theoretical one. A reason for this broadening is discussed by considering non-constant occupation probability of the conduction electrons caused by the electron-electron correlation. No crystalline anisotropy of the experimental directional profiles is found, being consistent with the theoretical results.
