Nuclear level densities

Canadian Journal of Physics, 1982
Nuclear level densities are obtained by first calculating the density for non-interacting particles using the Darwin–Fowler method and then folding in approximately the effects of the residual two-body interaction. For the former, the equations resulting from the method of steepest descent are solved numerically with a realistic set of single particle

Nuclear shell model and level density

International Journal of Modern Physics E, 2020
The accurate knowledge of the nuclear level density is crucial for understanding the nuclear structure and for numerous applications including astrophysical reactions. In this review paper, we discuss the shell-model description of the nuclear level density, the use of the statistical moments method and underlying physics. The level density found with

Nuclear level densities

Physical Review C, 1976
An improved expression for the nuclear level density is obtained by introducing a higher term in the expansion of the excitation energy in terms of nuclear temperature. The new term leads to better fitting with the experimental results especially at the high excitation energy part of the spectrum.

Nuclear level densities at high excitations

Physical Review C, 1992
We calculate level densities for {sup 20}Ne, {sup 40}Ca, and {sup 100}Ru nuclei using unrestricted uniform, single particle levels (Fermi gas) and for realistic levels restricted to those bound by centripetal and Coulomb forces. For the latter we use single particle levels due to Seeger, and results for a Woods-Saxon model.

NUCLEAR LEVEL DENSITY AT FINITE TEMPERATURES

International Journal of Modern Physics E, 2006
Selfconsistent mean-field calculations have been performed with the SkM* Skyrme force for 140 spherical even-even nuclei at temperatures 0≤T≤4 MeV . Single-particle level densities for this sample of nuclei are determined for various temperatures. The average dependence of the single-particle level density on mass number A and isospin is given and ...

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 ...
