Compton Profile of Nb–Mo Alloys

The electronic momentum densities and the Compton profiles in Nb 1- x Mo x alloys are calculated on the basis of the KKR-ATA scheme with three different alloy potentials. The peak widths of the spectral momentum density and the calculated Compton profiles are strongly influenced by the alloy potentials used. The effect of alloying with Mo can be seen in the changes of the fine structures on the calculated Compton profiles. It is demonstrated that measurements of the Compton profiles can provide information about the construction of realistic alloy potentials.
