Spin-resolved pair-distribution functions in an electron gas: A scattering approach based on consistent potentials

The spin-resolved pair-functions g↑↓(r) and g ↑↑(r) of an interacting unpolarized electron gas are calculated. The calculations are based on geminal representations of two-electron states and physically motivated model potentials, V ↑↓(r) and V↑↑(r), in the scattering Schrödinger equations for relat...
