Characteristic function of momentum density distribution. II

Abstract

Rigorous relations between the moments 〈plxpmypnz〉 and 〈pn〉 and the characteristic function B(r) of the momentum density distribution ρ(p) are here generalized to the case of negative l, m, and n. A simple application is given which illustrates that the present results enable us to obtain the moments of momenta without referring to any momentum‐space quantity.
