Scaling behavior of the Compton profile of alkali metals

Abstract

The contribution of the valence electrons to the Compton profiles of the alkali metals is calculated using density functional theory. We show that the Compton profiles can be modeled by a $q-$Gaussian distribution, which is characterized by an anisotropic, element dependent parameter $q$. Thereby we derive an unexpected scaling behavior of the Compton profiles of all alkali metals.
