“…The g factors of the 2 + 1 [48] and 4 + 1 [225] states in 134 Te are consistent with g(6 + 1 ), and hence the same configuration. In 132 Te, with two neutron holes, g(2 + 1 ) = +0.46(5) [206,210,226,227] is closer to the collective g ≈ Z/A ≈ 0.39, whereas g(6 + 1 ) = +0.78(8) [228] remains consistent with that of the pure π1g 2 7/2 configuration. Recent work at the Australian National University (ANU) tracks the persistence and eventual weakening of the proton-broken-pair structure in the 4 + states of 124,126,128,130 Te [115].…”

The present review takes steps from the domain of the shell model into open shell nuclei. The question posed in the title is to dramatize how far shell model approaches, i.e., many nucleons occupying independent-particle configurations and interacting through two-body forces (a configuration interaction problem) can provide a description of nuclei as one explores the structure observed where neither proton nor neutron numbers match closed shells. Features of doubly closed and singly closed shell nuclei and adjacent nuclei are sketched, together with the roles played by seniority, shape coexistence, triaxial shapes and particle–core coupling in organizing data. An illuminating step is taken here to provide a detailed study the reduced transition rates, B(E2;21+→01+), in the singly closed shell nuclei with doubly closed shell plus or minus a pair of identical nucleons, and the confrontation between such data and state-of-the-art shell model calculations: this amounts to a review of the effective charge problem. The results raise many questions and point to the need for much further work. Some guidance on criteria for sharpening the division between the domain of the shell model and that of deformation-based descriptions of nuclei are provided. The paper is closed with a sketch of a promising direction in terms of the algebraic structure embodied in the symplectic shell model.

“…In general, it is convenient to use 0 + *2 + ->-0 + cascades, which have a very large anisotropy and give large effects. For these cascades, R (9) has a maximum at about 150°. Consequently, three of the six angles were set at 150°, two at 120°, and one at 90°.…”

“…The results obtained using this experimental setup will be illustrated based on the case of well studied 132 Te [55][56][57][58][59][60][61][62]. Figure 9(a) shows the partial level scheme of 132 Te (below 4.3 MeV).…”

γ-ray spectroscopy of fission fragments is a powerful method for studies of nuclear structure properties. Recent results on the spectroscopy of fission fragments, using the combination of the AGATA γ-ray tracking array and the VAMOS++ large acceptance magnetic spectrometer at GANIL, are reported. A comparison of the performance of the large germanium detector arrays EXOGAM and AGATA illustrates the advances in γ-ray spectroscopy of fission fragments. Selected results are highlighted for prompt γ-ray spectroscopy studies, measurements of short lifetimes of excited states with the Recoil Distance Doppler-Shift method, using both AGATA and VAMOS++ and prompt-delayed γ-ray spectroscopy studies using AGATA, VAMOS++ and EXOGAM.
