G. Lazzari et Fv. Deblasio, PROTON SUPERFLUIDITY IN NEUTRON-STAR MATTER WITH AN EFFECTIVE INTERACTION, International journal of modern physics E, 4(4), 1995, pp. 843-848
The isotropic proton superfluidity in Neutron Star Matter is evaluated
in the conventional BCS approach using Gogny effective force as the n
ucleon-nucleon interaction. We have found that, neglecting the polariz
ability effects and including different proton concentrations in neutr
on star matter, the S-1(0) proton energy gap is considerably smaller t
han the corresponding neutron isotropic gap. It is shown that at highe
r densities proton superfluidity could prevail in a considerable range
of density in the interior of a neutron star.
