Abstract

One of the important methods for studying the structure of the nucleus is the thermodynamic description of the nucleus. Although the nucleus consists of a fermionic system with a few particles, it experiences thermal fluctuations in particle number. In this task, thermodynamic quantities such as the excitation energy, level density parameter, and nuclear level density have been calculated by taking into account temperature-dependent pairing correlation as well as the statistical and quantum fluctuations using the LN model. Furthermore, by putting the calculated level density parameter from the LN model into the level density relation derived from the BSFG model, the nuclear level density has been obtained using this approach. Finally, the computed level densities using the mentioned models have been compared with each other and with the experimental level density.
