In this paper directional Compton profiles of Mo are presented and the resu
lts compared with LCGO and APW model calculations. Both electronic structur
e models describe qualitatively the anisotropy of the electron momentum dis
tribution, which is influenced by the Fermi surface topology. However, the
absolute profiles indicate that electron-electron correlation effects are i
nadequately described within the local density approximation. (C) 2001 Else
