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

Abstract

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
