3P2 superfluidity of neutrons in neutron star matter is investigated using several potential models and the separation method. As a first step, the dependence of the pure 3P2 energy gap on the projection M of total momentum J is analyzed. The energy gap functions for pure 3P2 pairing are treated as vectors indexed by M, and it is shown that the magnitudes of these vectors at Fermi surface are close to each other, whereas their components are different. On the basis of these works, the influence of hyperons on the energy gap for 3P2 neutron pairing, with and without coupling to the 3F2 state, at Fermi surface in neutron star matter is studied. The results show that in the OPEG case hyperons increase the energy gap when the baryon number density is in the range of 0.2 fm-30.33 fm-3, and in the Argonne υ18 case hyperons increase the energy gap in the whole range where the 3P2 superfluidity exists. The energy gaps are zero in two types of neutron star matter for the Bonn potential.
