We discuss and clarify a simple and accurate interpolation scheme for the s
pin-resolved electron static structure factor (and corresponding pair corre
lation function) of the 3D unpolarized homogeneous electron gas which, alon
g with some analytic properties of the spin-resolved pair-correlation funct
ions, we have just published (Phys. Rev. B, in press). We compare our resul
ts with the very recent spin-resolved scheme by Schmidt et al. (Phys. Rev.
B 46 (1992) 12 497; 56 (1997) 7018; submitted for publication) and focus ou
r attention on the spin-resolved correlation energies and the high-density
limit of the correlation functions. (C) 2000 Elsevier Science B.V. All righ
