The momentum distribution of the unpolarized uniform electron gas in its Fermi liquid regime, n ( k , r s ), with the momenta k measured in units of the Fermi wave number and with the density parameter r s , is constructed assuming that n (0, r s ), n (1 ± , r s ), and the on‐top pair density as well as the kinetic correlation energy are known. Preliminary results for r s = 1 to 6 are presented.
