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.
