Ground state of nuclei in the Barium region within the Highly Truncated Diagonalization Approach

The ground state of some Barium isotopes has been investigated in the framework of the parity-symmetry projection of the Highly Truncated Diagonalization Approach (HTDA), which is suited to treat the correlations in an explicitly particle-number conserving microscopic approach. A Skyrme energy -density functional using the SkM∗ interactions has been considered to treat the particle-hole channel, whereas a density-independent δ force has been adopted for the residual interaction. The obtained results are compared with the previous calculations using the Woods-Saxon potentials
