Résumé |
Nuclear superfluidity is an absolutely fascinating phenomenon: due to a resid-
ual interaction, two fermion can couple and form a Cooper pair. The formation
of the pairs impact macroscopic properties of the system. This was illustrated
in the seminal paper of Bohr, Mottelson and Pines, by inspecting the excita-
tion spectra of even-even and odd-odd nuclei. A lot of theoretical work has
been done to investigate pairing correlations and their possible impact on the
properties of the nuclear system. Despite such an effort several open questions
concerning the underlying structure of the pairing interaction is still unknown.
How to improve our knowledge? In my talk, I will focus on the description of
pairing properties within Nuclear Energy Density functional theory by illus-
trating how particular assumptions on the pairing interaction may have large
effects on some particular experimental observables. The talk aims at trigger-
ing a discussion between theory and experiment on future plans on how to
tackle such a complicated, but definitely fascinating problem. |
