Coexistence of isospin I = 0 and I = 1 pairings in asymmetric nuclear matter *

The coexistence of neutron-neutron (n-n), proton-proton (p-p), and neutron-proton (n-p) pairings is investigated by adopting an effective density-dependent contact pairing potential. These three types can coexist only if the n-p stronger than n-n p-p for isospin asymmetric nuclear matter. In addition, existence pairs might enhance in matter when strength significantly ones. Conversely, reduced interaction approaches pairings.
