Abstract: Nuclear level densities (NLD) are fundamental input parameters in nuclear reaction cross-section calculations and evaluations. Those for medium and heavy nuclei are significant to nuclear energy and non-energy applications. At present, investigations on NLD are mostly performed through empirical formulas. Many important properties are based on simple assumptions like parity and...

The determination of the nuclear level densities is of particular importance in a large number of nuclear applications. They indeed govern the decay process from the compound nucleus and are mandatory when dealing with capture cross sections. For decades, theoretical estimates of nuclear level densities have relied on phenomenological models whose parameters are fitted to experimental data....

The determination of the nuclear level densities is of particular importance in a large number of nuclear applications. Most of existing theoretical estimates of nuclear level densities rely on empirical or phenomenological models essentially fitted to experimental data. Although such adjustments respond to the high accuracy needs of some nuclear applications, their predictive power remains...
