| 英文摘要 | The proton and neutron S-1(0), pairing gaps in beta-stable neutron star matter have been studied by using the isospin dependent Brueckner-Hartree-Fock approach and the BCS theory. We have concentrated on investigating and discussing the effect of three-body force. The calculated results indicate that the three-body force has only a small effect on the neutron S-1(0) superfluidity in beta-stable neutron matter, i.e., it leads to a small reduction of the neutron S-1(0) paring gap. However the three-body force not only suppresses strongly the strength of the proton S-1(0) superfluidity in beta-stable neutron star matter but also reduces largely the density domain for the proton S-1(0) superfluidity phase from rho(B) < 0. 45fm(-3) to rho(B) < 0.3fm(-3). It is also shown that the three-body force enhances largely the proton fraction in beta-stable neutron star matter at high densities. |
