Electron momentum density distribution in TiCu

The electron momentum density distribution in intermetallic TiCu is measured and compared with calculations based on linear combination of atomic orbitals (LCAO) and spin polarized relativistic Korringa-Kohn-Rostoker (SPR-KKR) methods. The spherically averaged theoretical Compton profiles are in good agreement with the measurement. The better agreement is, however, shown by the SPR-KKR method. To investigate the bonding mechanism in the alloy, the density of states has also been determined from SPR-KKR method.
