Nucleon Superfluidity in Asymmetric Nuclear Matter and Neutron Star Matter

摘要

We have investigate the nucleon superfluidity in asymmetric nuclear matter and neutron star matter by using the Brueckner-Hartree-Fock approach and the BCS theory. We have predicted the isospin-asymmetry dependence of the nucleon superfluidity in asymmetric nuclear matter and discussed particularly the effect of microscopic three-body forces. It has been shown that the three-body force leads to a strong suppression of the proton ~1S_o superfluidity in β - stable neutron star matter. Whereas the microscopic three-body force is found to enhance remarkably the ~3PF_2 neutron superfluidity in neutron star matter and neutron stars.
