Phase Transition and Level Density of Atomic Nuclei

Mass-number and excitation-energy dependence of the spin cutoff parameter

“…Calculated spin cutoff parameters were obtained using a formalism proposed by Sano and Yamasaki [10] and Morretto [11]. The nucleus is assumed to have a BCS (superconductor) Hamiltonian.…”

Statistical description of a paired nucleus with the inclusion of angular momentum

“…(10) with respect to ~. keeping n k and n k constant one obtains: (11) where (12) The quantity !J. is called the "gap parameter" and it is a measure of the pairing correlation.…”

“…with respect to the first analytical nuclear level density formula proposed by Bethe [11]. Level densities have been studied for finite temperatures within the BCS model [12,13]. Today, Monte Carlo shell model calculations [14,15] are able to estimate nuclear level densities [16] for heavy mid shell nuclei like 162 Dy [17].…”
