摘要
An approximation for the unknown two-electron wavefunctions (geminals) of the interacting uniform electron gas is found, starting from the effective screened Coulomb potential proposed by Overhauser [Can. J. Phys. 73, 683 (1995)]. The short-range part (small electron-electron distances) of the corresponding pair density is in accurate agreement with the Quantum Monte Carlo results.
