Abstract 59.54 keV γ‐ray Compton profiles of CaF 2 along the [100] and [110] directions are reported. Both, the absolute profiles and their anisotropy are derived from the LCAO model and compared with experiments. One‐dimensional Fourier transforms are determined from both, experimental and theoretical profiles and compared with each other. Theoretical results are found to be in qualitative agreement with the experiments. It is also shown that momentum distributions are more sensitive to anisotropy in electron distributions than X‐ray structure factors.
