A Survey of Nuclear Level Density Theories

1972
The theory of nuclear level density is about as old as nuclear physics itself. Actually, many features of the models used in present days are already found in the famous article published by H.A. Bethe in 1937[1]. To a considerable extent, the theory of nuclear level density rests upon models which describe nuclei as made of independent objects, which ...

Some features of the calculated nuclear level density

Nuclear Physics, 1966
Abstract Formulae for the nuclear level density as a function of the angular momentum, the SU 3 quantum numbers and the nuclear deformation parameter are derived. The calculated level densities as function of the angular momentum are compared with an experimental result for 28 Al. The agreement is not good for high spin values. The need for further

Nuclear level density and partitions of an integer

Journal of Physics G: Nuclear and Particle Physics, 2005
An improved calculation of the nuclear level density using equally spaced single nucleon states is presented. The calculation involves a modification of the well-known Laplace transform method. For values of the excitation energy which are integral multiples, K, of the single particle spacing, the new derivation is tested by calculating the number of ...

Testing basic phenomenological models of nuclear level density

Physics of Particles and Nuclei, 2006
The problem of phenomenological description of nuclear level density is analyzed on the basis of testing the most important models: the Fermi gas and the generalized superfluid models and their modifications. Experimental data and numerical results for different characteristics related to the description of the level density as a function of excitation

Influence of pairing correlations on nuclear level densities

Nuclear Physics, 1964
Abstract The influence of pairing correlations on the level density of a nucleus is studied by employing a Fermi gas model with equally spaced single particle levels and treating the pairing interactions in the superconductivity formalism of Belyaev and others.

Limits Of Thermodynamic Models for Nuclear Level Densities

1980
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 the result that some of the undesirable assumptions originally required by the model are no longer necessary. Some problems remain, however, particularly in calculating level densities
