Directional Compton Profiles and Energy Bands of Palladium

Abstract

The directional Compton profiles of palladium along [100] and [110] directions have been measured using 100 mCi 241Am Compton spectrometer. The theoretical Compton profiles and energy bands have been computed using hybridisation of Hartree-Fock and density functional theory. Except some fine structures, the energy bands are in good agreement with the available data. The measured anisotropy is found to be smaller than the present calculations and the available augmented plane wave and linear combination of Gaussian type orbitals based profiles. The experimental profiles are interpreted in terms of energy bands of Pd and Fermi surface topology.
