“…As far as the quadrupole moments are concerned, 4 out of the 5 calculated values are within the error bars and the observed signs, when measured, are correctly reproduced. It is worth noting that our results do not differ significantly from those obtained using an effective proton charge e eff p = 1.5e, which is consistent with the values adopted by other authors [16,17].…”

“…As already mentioned in the Introduction, the first attempt to employ in this region effective interactions derived from the free nucleon-nucleon potential dates back to the early 70s [17]. In that work, however, the Hamada-Johnston NN potential was used and only the 3p-1h core-polarization diagram (the so-called bubble) was included in the calculation of the effective interaction.…”

“…On the other hand, the good doubly magic character of 208 Pb has motivated many shell-model calculations in this region. In all the calculations performed so far, however, phenomenological interactions have been used [15,16], the only notable exception being the pioneering work of McGrory and Kuo [17], where the KH interaction was employed.…”

We have performed shell-model calculations for the N = 126 isotones 210 Po, 211 At, and 212 Rn using a realistic effective interaction derived from the Bonn A nucleon-nucleon potential by means of a G-matrix folded-diagram method. The calculated binding energies, energy spectra and electromagnetic properties show remarkably good agreement with the experimental data. The results of this paper complement those of our previous study on neutron hole Pb isotopes, confirming that realistic effective interactions are now able to reproduce with quantitative accuracy the spectroscopic properties of complex nuclei.

New high-spin microsecond isomers, with J π =(31 + ) and J π =(28 − ), have been identified in 206 Bi at 10170 and 9233 keV, respectively, using γ-ray coincidence spectroscopy following deep-inelastic reactions with the 76 Ge+ 208 Pb system. Yrast and near-yrast levels populated in the decay of these isomers have been located and interpreted with the help of shell-model calculations. The states identified at energies up to approximately 7 MeV can be described well in terms of one-protonparticle, three-neutron-hole couplings.

“…In a previous study of these levels, Chou and Warburton, in the absence of a renormalized G matrix for the 132 Sn core, used a set of matrix elements taken from studies of valence particle and hole spectra around 208 Pb that were scaled by a factor of (208/132) −1/3 , as estimated by the mass dependence of a finite range interaction in an oscillator basis [1,[13][14][15]. As reported by Korgul et al, there was agreement with experiment at a degree that is perhaps unexpected [4].…”

The level structure of odd-odd 134 Sb has been studied at CERN/ISOLDE following the β − decay of 134 Sn and the β-delayed neutron decay of 135 Sn. Elemental and isobaric separation were accomplished by use of a resonance ionization laser ion source and an on-line mass separator, respectively. Both γ -ray singles and γ -γ coincidence data were taken as a function of time. New levels at 279, 441, 555, 617, and 1385 keV have been identified and given proposed spin and parity assignments of 7 − , 5 − , 6 − , 4 − , and 5 − , respectively, following β-delayed neutron decay of 7/2 − 135 Sn. New 1 − levels have been identified at 1900, 2170, and 2430 keV following the β − decay of 0 + 134 Sn. The resulting level structures are compared to shell-model calculations using the CD Bonn interaction and scaled and unscaled Kuo-Herling interactions developed for the 208 Pb region. Remarkably enough, the unscaled Kuo-Herling interaction provides the best fit for the levels below 1 MeV.
