Abstract
Finite-temperature Hartree-Fock-Bogoliubov calculations are performed in
72Ti
by using Skyrme interactions, to predict
the finite-temperature pairing re-entrance phenomenon for the system of neutrons. It is also shown that pairing re-entrance
modifies the neutron single-particle energies around the Fermi level, as well as the occupation numbers and quasiparticle
levels. It is also shown that neutron resonant states are expected to contribute substantially to pairing correlations and the
two predicted critical temperatures are
1 0.1 0.2 T MeV c
and
T MeV c2 0.7 0.9
. On the other hand, our results for the
ground-state energies, proton and neutron separation energies are in very good agreement with experiment where available.
