Abstract

The nuclear level density and thermal properties of ⁵⁶Fe have been extracted using the BCS Hamiltonian with inclusion of interacting fermions. Single particle levels for Nilsson potential have been used in the calculations. The shape of the energy and entropy curves has been interpreted as indication of a double phase excitation region and proposed as signature of the pairing phase transition. The results are compared to the experimental data obtained by the Oslo group.
