The Shell Correction Method and Its Application to Nuclear Masses
The calculation of nuclear masses within the Nilsson-Strutinsky method is briefly reviewed. In numerical calculations, the standard liquid drop or droplet model is used for the macroscopic energy and the microscopic energy is calculated from the single-particle orbitals of the modified oscillator potential. Results for nuclei with A≳90 are presented. Except for some closed shell nuclei, the discrepancies between experimental and theoretical shell effects seldom exceed 1 MeV. For medium-heavy nuclei and outside the regions where the parameters have been fitted, the general trends appear to be much better described within the liquid drop than within the droplet model.
