Calculations of the Compton profiles for the transition metals Ta and W are performed, using electron wave functions obtained from self‐consistent augmented plane wave (APW) band structure calculations within the local density formalism of Hedin‐Lundqvist. Relativistic effects are included except for the spin‐orbit interaction. The observed structures of the Compton profiles in these metals are understood in terms of the topology of their Fermi surfaces.
