Momentum distributions and compton profiles of copper and aluminium

Abstract

The many body ground state properties of momentum distribution and Compton profiles have been calculated under the Kohn-Sham density functional formalism for solid copper and aluminium. A linear combination of Slater type orbitals (LCSTO) was used in the single particle Kohn-Sham equations to calculate the particle density, ρ(x), and the effective potential, Veff(x). The crystal structure was employed by expansion of functions to first order in nearest neighbours. The particle momentum distributions and associated Compton profiles were then calculated.
