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 ...

Approximation for shell-model level densities

Physical Review C, 1988
The maximum entropy approach for the calculation of nuclear shell-model level densities developed in a previous paper is extended to the calculation of terms of higher order inNk−1, whereNK is the dimension of the shell-model subspaces of interest. We present terms of first and second order inNk−1, i.e.

The characteristic level and the nuclear level density

Nuclear Physics, 1958
Abstract The suggestions put forward by Bethe and Hurwitz that level densities ought to be measured from a standard energy, such as is given by the semi-empirical formula, and not from nuclear ground states is considered. The semi-empirical formula is corrected, following P. Fong, and this “characteristic level” is determined for nuclei from A = 10

Level Densities from Excitation Functions of Isolated Levels

Physical Review, 1969
Thick-target excitation functions were measured for the reactions ${\mathrm{Co}}^{59}(p,{\ensuremath{\alpha}}_{0}){\mathrm{Fe}}^{56}$, ${\mathrm{Co}}^{59}(p,{\ensuremath{\alpha}}_{1}){\mathrm{Fe}}^{56}$, ${\mathrm{Co}}^{59}(p,{\ensuremath{\alpha}}_{2}){\mathrm{Fe}}^{56}$, ${\mathrm{Mn}}^{55}(p,{\ensuremath{\alpha}}_{0}){\mathrm{Cr}}^{52}$, ${\mathrm{Mn}

Nuclear level densities and level spacing distributions

1986
Extensive and complete level schemes and neutron resonance densities of 72 nuclides have been used to determine the spin cut-off parameter, parameters for level density formulae and level spacing distributions. The level spacing distributions indicate either very different nuclear structures or the existence of a further good quantum number at low ...

Nuclear Level Density Parameter

2008
The nuclear level-density parameters obtained in the Yukawa folded potential approach are presented. The particle-number averaging ({N} averaging) Strutinsky shell-correction method is used to extract the shell-correction energy and its change with temperature and the macroscopic nuclear energy for 130 spherical even-even nuclei.
