Limits Of Thermodynamic Models for Nuclear Level Densities

摘要: The current status of thermodynamic models as applied to nuclear level densities is reviewed. Considerable refinement has taken place during the last fifteen years, with result that some undesirable assumptions originally required by model are no longer necessary. Some problems remain, however, particularly in calculating for deformed nuclei. Furthermore, related parameters, such positive-parity negative-parity ratio levels and spin cutoff parameter more sensitive presence two-body interactions than total density. Improvement our characterization will require use techniques which can incorporate effects density calculation.
