SYSTEMATICS OF NUCLEAR LEVEL DENSITY PARAMETERS

Capture Gamma-Ray Spectroscopy and Related Topics, 2003
The level density parameters for backshifted Fermi gas (both without and with energy-dependent level density parameter) and constant-temperature models have been determined for 310 nuclei between $^{18}\mathrm{F}$ and $^{251}\mathrm{Cf}$ by fitting of the complete level schemes at low excitation energies and s-wave neutron resonance spacings at the ...

Macroscopic systematics of nuclear level densities

Nuclear Physics A, 1980
Abstract In a number of recently proposed semi-empirical nuclear level density formulae, a macroscopic-microscopic approach similar to that used in nuclear potential energy calculations has been successfully used. While the underlying macroscopic part in these formulae is the well-known Bethe expression, these fomulae differ in the treatment of the ...

Statistical Treatment of Nuclear Level Densities

Physica Scripta, 2002
Nuclear level densities and thermodynamic functions have been determined for light A nuclei, from a microscopic theory, which includes nuclear pairing interaction. Nuclear level densities have also been obtained using Bethe formula as well as constant temperature formula. Level densities extracted from the theories are compared with their corresponding

Mean-field description of nuclear level densities

Nuclear Physics A, 1985
Abstract For a rigorous independent-particle approach to the nuclear level-density problem we use a Perey-Buck potential as a realistic representative for the momentum- and energy-dependent single-particle potential. The level-density parameter — including a surface correction — is obtained from a closed formula as well as directly by a Strutinsky ...

Fermi gas descriptions of nuclear level densities

Annals of Physics, 1991
Abstract In this paper the derivation of nuclear level densities from a Fermi gas treatment of the nucleons is surveyed. In fact, there are three classes of Fermi gas models: the infinite, in which an unlimited number of fermions are available for excitation, the finite, in which this number is finite but the single-particle spectrum is unbounded ...

Theory of Nuclear Level Density

Physical Review, 1954
We have compared the level density of a nuclear model deduced from a statistical analysis with the results of the exact counting of the levels of the same model. The tables of levels of ${\mathrm{Ne}}^{20}$ given by Critchfield and Oleksa have been used as a test of the statistical theory. A new derivation of the level density is presented.
