Abstract

The one-electron momentum distribution function 〈aa〉 for an electron gas is investigated by a diagrammatic analysis of perturbation theory. It is shown that 〈aa〉 has the following exact asymptotic form for large k (k ≫ pF; pF, the Fermi momentum): 〈aa〉 = 4 9( αrs π)2×( pF8 k8) g{double arrow, left up, right down}(0) + ⋯, where g{double arrow, left up, right down}(0) is the zero-distance value of the spin-up-spin-down pair correlation function. The physical implications of the above asymptotic form are discussed.
