| Abstract: | We investigate the 3PF2 neutron superfluidity in β-stable
neutron star matter and neutron stars by using the BCS theory and
the Brueckner--Hartree--Fock approach. We adopt the Argonne V18
potential supplemented with a microscopic three-body force as the
realistic nucleon--nucleon interaction. We have concentrated on
studying the three-body force effect on the 3PF2 neutron pairing
gap. It is found that the three-body force effect is to enhance
remarkably the 3PF2 neutron superfluidity in neutron star matter
and neutron stars. |
