A band structure calculation of the photon‐pair momentum density distributions (TPMD) and electron momentum density for Compton scattering (EMD) in f.c.c. Mn is made employing Hubbard's approximate scheme. The results of the present calculations for TPMD and EMD in Mn along [100], [110], and [111] directions are analysed in terms of their respective band structures. A comparison of the TPMD results with the EMD shows that the high‐momentum component is much higher in the case of EMD. The results of ACPAR and CP are also presented.
