The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. In recent calculations the nuclear level density{emdash}as an important ingredient to the statistical model (Hauser-Feshbach){emdash}has shown the highest uncertainties. We present a global parametrization of nuclear level densities within the back-shifted Fermi-gas formalism. Employment of an energy-dependent level density parameter a, based on microscopic corrections from a recent…

Large-scale prediction of the parity distribution in the nuclear level density and application to astrophysical reaction rates
A generalized method to calculate the excitation-energy dependent parity ratio in the nuclear level density is presented, using the assumption of Poisson distributed independent quasi particles
Statistical nuclear properties (level densities, spin distributions)
A general overview is given on the phenomenological methods used to describe the level densities in nuclei. Two well-known two-parameter formulas of level densities, the Back-Shifted Fermi Gas (BSFG)
Measurement of (α,n) reaction crosssections of erbium isotopes for testingastrophysical rate predictions
The γ-process in core-collapse and/or type Ia supernova explosions is thought to explain the origin of the majority of the so-called p nuclei (the 35 protonrich isotopes between Se and Hg).
Sensitivity of nuclear statistical equilibrium to nuclear uncertainties during stellar core collapse

Continuum corrections to the level density and its dependence on excitation energy, n-p asymmetry, and deformation
In the independent-particle model, the nuclear level density is determined from the neutron and proton singleparticle level densities. The single-particle level density for the positive-energy
Cross section measurements of proton capture reactions on Sr isotopes for astrophysics applications
Background: Abundance calculations of a certain class of proton-rich isotopes, known as $p$ nuclei, require knowledge of the cross sections of thousands of nuclear reactions entering a reaction
Nuclear Reactions of Astrophysical Interest
We present different reaction models commonly used in nuclear astrophysics, in particular for the nucleosynthesis of the light elements. Nuclear reactions involved in stellar evolution generally
Systematics of nuclear level density parameters
The level density parameters for the back-shifted Fermi gas (both without and with energy-dependent level density parameter) and the constant temperature models have been determined for 310 nuclei


Fermi-Gas Model Parametrization of Nuclear Level Density.
The authors furnish a new parametrization of the Fermi-Gas model description of nuclear level densities at excitation energies corresponding to the neutron binding energy. The model adopted is the

Role of the symmetry energy in atomic mass formulas.
Cameron has interpreted the heavy uranium mass yield curve from the Mike thermonuclear explosion as indicating that conventional atomic mass formulas do not give realistic values of neutron binding
Nuclear ground state masses and deformations
Abstract We tabulate the atomic mass excesses and nuclear ground-state deformations of 8979 nuclei ranging from 16O to A = 339. The calculations are based on the finite-range droplet macroscopic
