Comparison between the exact and the thermal description of the pairing interaction in Sn114

The pairing interaction is solved exactly in the Sn114 nucleus using a realistic strength parameter as well as standard energy levels for the shell seniority zero states. The same single-particle and two-body Hamiltonian is treated with finite-temperature BCS and the thermal random-phase approximati...
