Combinatorial Study of Nuclear Level Density for Astrophysical Applications
Abstract
We present some results and remarks based on a combinatorial approach of the evaluation of the nuclear level density. First, we show that it is possible to extract some reliable information from the output of the program whose rough data present a strong statistical fluctuation from bin to bin. This includes smoothing and evaluation of the desired quantities. After some comments about the spin and parity distributions, we consider the question of the non-equipartition of parities, mainly, at low energies. Finally, we present a simple model to include and test this effect in the computation of thermonuclear reaction rates.
