Directional Compton profiles of single crystals of bismuth, Bi[100], Bi[110] and Bi[111] have been measured with high accuracy for the first time using 662 keV γ‐radiation from a 137 Cs isotope source. Korringa‐Kohn‐Rostoker (KKR) semi‐relativistic calculations were performed to calculate the theoretical electron momentum density distributions along the three main crystallographic directions. The calculated and measured Compton profiles agree very well in periodicity of the oscillatory character of directional Compton anisotropies whereas the predicted amplitude of the oscillations is twice that measured in the experiment.
