Abstract：
The neutron ³PF₂ pairing gap in pure neutron matter, neutron ³PF₂ gap and neutron-proton ³SD₁ gap in symmetric nuclear matter have been studied by using the Brueckner-Hartree-Fock(BHF) approach and the BCS theory. We have concentrated on investigating and discussing the three-body force effect on the nucleon superfluidity. The calculated results indicate that the three-body force enhances remarkably the ³PF₂ superfluidity in neutron matter. It also enhances the ³PF₂ superfluidity in symmetric nuclear matter and its effect increases monotonically as the Fermi-momentum k_F increases, whereas the three-body force is shown to influence only weakly the neutron-proton ³SD₁ gap in symmetric nuclear matter.
