“…The values obtained are close to our microscopic results, but the fitted operator does not include the tensortype correction obtained microscopically. The calculations of Sarkar and Sarkar [3] are based on a fitted interaction for N = 82 plus a renormalized G matrix extrapolated from the region of 208 Pb for N > 82. Their wavefunctions for N = 82 should be comparable in accuracy to the present model.…”

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.

“…In particular, the nuclides 135 I, 135 Te, 135 Sb, and 135 Sn remain an excellent testing ground for descriptions of nuclei with only three nucleons present beyond the 132 Sn double shell closure. Relatively detailed data have been available for some time for 135 I and 135 Te [5,6].…”

The β decay of 135 Sn was studied at CERN/ISOLDE using a resonance ionization laser ion source and mass separator to achieve elemental and mass selectivity, respectively. γ -ray singles and γ -γ coincidence spectra were collected as a function of time with the laser on and with the laser off. These data were used to establish the positions of new levels in 135 Sb, including new low-spin states at 440 and 798 keV, which are given tentative spin and parity assignments of 3/2 + and 9/2 + , respectively. The observed levels of 135 Sb are compared with shell-model calculations using different single-particle energies and different interactions.

“…In this regard, it is of key importance the fact that, given the correspondence between the SP levels, the matrix elements of the effective interactions in 132 Sn and 208 Pb regions are expected to be proportional to one another. This has stimulated several shellmodel calculations on nuclei around 132 Sn [12,13,14] with two-body effective interactions originating from the modified version [15] of the Kuo-Herling interaction [16], originally designed for the Pb region. However, these attempts have not been successful, as discussed for instance in [14], where the conclusion was drawn that a consistent Hamiltonian for the three nuclei beyond the N = 82 shell closure, 134 Sb, 135 Sb, and 134 Sn, had yet to be found.…”

Starting from the striking similarity of proton-neutron multiplets in 134 Sb and 210 Bi, we perform a shell-model study of nuclei with two additional protons or neutrons to find out to what extent this analogy persists. We employ effective interactions derived from the CD-Bonn nucleon-nucleon potential renormalized by use of the V low−k approach. The calculated results for 136 Sb, 212 Bi, 136 I, and 212 At are in very good agreement with the available experimental data. The similarity between 132 Sn and 208 Pb regions is discussed in connection with the effective interaction, emphasizing the role of core polarization effects.PACS numbers: 21.60. Cs, 21.30.Fe, 27.60.+j, 27.80.+w Since its advent more than fifty years ago, the shell model has been the basic framework for understanding the structure of complex nuclei in terms of individual nucleons. Within this model, nuclei around doubly closed shells play a special role. In fact, they yield direct information on the two basic ingredients of the model: singleparticle (SP) energies and matrix elements of the effective interaction. This makes them the best testing ground for realistic shell-model calculations where the effective interaction is derived from the free nucleon-nucleon (N N ) potential.For a long time our knowledge of nuclei with fewvalence particles or holes has been mostly limited to neighbors of stable or long-lived doubly magic 16 O, 40 Ca, 48 Ca, 56 Ni, and 208 Pb. However, during the last decade there has been substantial progress in the experimental study of nuclei far from the stability line, and the development of radioactive nuclear beams is currently giving strong impetus to the study of exotic nuclei around 78 Ni, 100 Sn, and 132 Sn. These new data pose challenging questions about the evolution of the shell structure, as for instance the validity of magic numbers when moving far away from stability and the existence of possible changes in the mean field as well as in the two-body interaction [1,2,3].In this context, nuclei "north-east" of 132 Sn are of special interest, since in recent experiments some peculiar properties have been observed which might be interpreted as the onset of a shell-structure modification (see introductory discussion in [4]). To investigate whether these features really depend on the exoticism of 132 Sn neighbors, we believe that a comparative study of their spectroscopic properties and those of nuclei close to stable 208 Pb is desirable.As is well known, 132 Sn and 208 Pb, which are very differently located with respect to the valley of stability, both exhibit a strong neutron-proton asymmetry and strong shell closures. The existence of a specific resemblance between 132 Sn and 208 Pb regions was pointed out long ago in Ref. [5], where it was noticed that every SP proton or neutron state in the 132 Sn region, characterized by quantum numbers (n l j), has its counterpart around 208 Pb with quantum numbers (n l + 1 j + 1). Based on this resemblance, the discrepancies between experimental and Woods-Saxon SP energies ...
