“…This is due to the presence of the d 3/2 shell, which is emptied first before the h 11/2 orbital. From the A = 128-130 values one may conclude that the choice of an effective charge of 0.70e, as taken from the literature [57], is probably on the low side and a value of 0.85e would be more appropriate [13,36]. This increase, however, would not cure the discrepancy observed toward mid-shell, which clearly indicates a too fast emptying of the h 11/2 orbital.…”

New sub-µs isomers have been observed in the neutron-rich Sn isotopes. 125,127,129 Sn nuclei have been produced in a relativistic fission reaction of 238 U on a 9 Be target at 750 A·MeV and by the fragmentation of 136 Xe at 600 A·MeV populating high-spin yrast states. In addition to the already known µs isomers, three new ones with sub-µs half-lives have been observed. These yrast isomers are the high-spin members of the ν(d −1 3/2 h −2 11/2 ) and νh −n 11/2 , seniority v = 3 multiplets leading to isomeric (23/2 + ) and (27/2 − ) states, respectively. Added to the already known 19/2 + µs isomers in this region the current work completes the systematic information of neutron-hole excitations toward the filling of the last h 11/2 orbital at N = 82. The results are discussed in the framework of state-of-the-art shell-model calculations using realistic interactions.

“…[14] the nn Hamiltonian based upon the CD-Bonn G matrix was used to study the the Sn isotones. Our results for 130 Sn were similar to these previous calculations, but differ due to the new energy for the h 11/2 level in 131 Sn [9].…”

Development of neutron-rich radioactive beams at the Holifield Radioactive Ion Beam Facility has stimulated experimental and theoretical activity in heavy Sn and Te isotopes. Recently, the g factor of the first 2 + state in 132 Te has been measured. We report here new shell-model calculation of magnetic moments for selected Sn and Te isotopes. The residual interaction is based on the CD-Bonn renormalized G matrix. Single-particle spin and orbital effective g factors are evaluated microscopically including core polarization and meson exchange currents effects.

“…Particularly important for this goal are determining the effective nuclear force unambiguously and establishing methodology of many-body problems which treats many-body correlations appropriately and accurately. This also applies to the shell model, one of the most successful nuclear-structure models in light to medium-heavy mass regions [1][2][3][4]. As for the former issue, although microscopic theories of effective interaction have been developed over decades, some empirical corrections are still needed for describing a wide range of nuclei belonging to a given shell.…”

Abstract. We report on our recent advancement in the shell model and its applications to exotic nuclei, focusing on the shell evolution and large-scale calculations with the Monte Carlo shell model (MCSM). First, we test the validity of the monopole-based universal interaction (V MU ) as a shell-model interaction by performing large-scale shellmodel calculations in two different mass regions using effective interactions which partly comprise V MU . Those calculations are successful and provide a deeper insight into the shell evolution beyond the single-particle model, in particular showing that the evolution of the spin-orbit splitting due to the tensor force plays a decisive role in the structure of the neutron-rich N ∼ 28 region and antimony isotopes. Next, we give a brief overview of recent developments in MCSM, and show that it is applicable to exotic nuclei that involve many valence orbits. As an example of its applications to exotic nuclei, shape coexistence in 32 Mg is examined.
