Abstract
The nucleon-nucleon correlations of asymmetric nuclear matter (ASM) in the 3S1-3D1 and the 3P2-3F2 states with the AV18 and the AV’6 potentials are studied in the lowest order constrained variational (LOCV) method. In these computations, the tensor (or the spin-orbit) correlations are considered in the 3S1-3D1 (3P2-3F2) state. The energy, as well as the healing distance of the ASM in the mentioned states, are reported. It is demonstrated that by decreasing the proton to neutron ratio, the non-central correlations (healing distances) of the coupled states grow. It is shown that the ASM non-central correlations and energies in the 3P2-3F2 state are more sensitive to the interaction than those of 3S1-3D1 state.
