Structural properties of symmetric bound nuclei in the effective 3-body model within the Faddeew Approach

We study new specific properties of odd-odd symmetric bound nuclei by using three-body model system calculations within the Faddeev scheme. In order to investigate the ground state properties with Woods-Saxon potential with spin-orbit effects, we first describe the model Hamiltonian for odd-odd symmetric nuclei, assuming the core+p+n picture. One set of the model Hamiltonian was introduced for the entire mass region to disentangle the role of the isoscalar spin-triplet pairing interaction near the ground state of these nuclei. Our results such as valence neutron and proton separation energies in s-wave sector (J^π=1^+), neutron pairing gaps, spin-orbit effects, energy differences between the spin-singlet and the spin-triplet in terms of obtained binding energies for 14N, 18F, 30P and 58Cu, is in good compatible with the achievement of experimental data.
