Temperature-dependent isovector pairing gap equations have been recently established using a path integral approach [1]. In the present work, the expressions of the main usual statistical properties, that is, the energy, the entropy and the heat capacity are established within the same model. These expressions generalize the Finite Temperature BCS (FTBCS) ones for the pairing between like-particles. Numerical calculations are carried out within the one-level model. The obtained results are compared to those of the usual FTBCS approach for the pairing between like-particles.
