Abstract: (Elsevier)
In order to formulate a statistical model of nuclear properties we combine the Thomas-Fermi assumption of two fermions per h 3 of phase space with an effective interaction between nucleons that contains seven adjustable parameters. After allowing for shell effects, an even-odd correction and a congruence energy (“Wigner Term”), six of the seven parameters were fitted to 1654 ground state masses of nuclei with N , Z ⩾ 8, together with a constraint that ensures agreement with measured values of the nuclear surface diffuseness. The RMS deviation in the fit to masses was 0.655 MeV, and the calculated values exhibit no drastic discrepancies even for A = 3.
