Calculating the nuclear mass in the very high angular momentum regime

Abstract

Macroscopic-microscopic methods are applied in the high-spin regime to calculate the nuclear binding energy (``mass'') as a function of proton number, neutron number, and angular momentum. Masses at high spin are calculated using the cranked Nilsson-Strutinsky model together with two different liquid drop models, the Lublin-Strasbourg drop model and the finite range liquid drop model. When comparisons are made with experimental data, a similar agreement between theory and experiment is obtained as for ground-state masses.
