Mic–Mac model based on the Wigner–Kirkwood method

NUCLEAR STRUCTURE A<120; analyzed available data; deduced binding energies, ground-state properties of these 551 nuclei using the well-known Finite Range Droplet Model and the Lublin–Strasbourg Drop Model, the Gogny forces within an Extended Thomas-Fermi approximation, Mic–Mac model using the Gogny D1S (D1M) force gives a fairly good description of the ground-state energies with a rms deviation of 834 keV (819 keV).
