Description

Nuclear self-consistent mean field result in appearance of series of single-particle states [1, 2], which can be obtained within Folded Yukawa Potential [3, 4]. Combinatorial method is developed to calculate level density $\rho$. In this approach, it's possible to also get metastable states, leading to altering level density and effecting nuclear cross sections of, in particular, astrophysical purpose [6], which were calculated in TALYS software package [5] with the implementation of obtained level density.
