They are also shown in the The experimental results systematically lie between the two calculated curves indicating possible shape mixing in the 74 Kr ground state. Similar results were obtained if one uses the Sk3 interaction.…”

“…The x-ray spectrum and the gates are shown in figure 2 of the original paper, where we can see clearly, from the fact that there are no Se x-rays visible, that there is no contamination from the daughter decay. The analysis was again carried out as described earlier and figure 15 shows the accumulated B(GT) distribution as a function of excitation energy in the daughter 74 Br nucleus. The results are compared with the calculations for b 2 = −0.15 and +0.39, the minima found in the PES in this case with the SG2 interaction.…”

Beta decay studies with the total absorption technique B Rubio, W Gelletly, E Nácher et al.Towards detailed knowledge of atomic nuclei -the past, present and future of nuclear structure investigations at GSI J Gerl, M Grska and H J Wollersheim Beta decay studies with total absorption spectroscopy and the Lucrecia spectrometer at ISOLDE Here we present the experimental activities carried out at ISOLDE with the total absorption spectrometer Lucrecia, a large 4π scintillator detector designed to absorb a full gamma cascade following beta decay. This spectrometer is designed to measure β-feeding to excited states without the systematic error called Pandemonium. The set up allows the measurement of decays of very short half life. Experimental results from several campaigns, that focus on the determination of the shapes of β-decaying nuclei by measuring their β decay strength distributions as a function of excitation energy in the daughter nucleus, are presented.

The method was designed for precision measurements with low-intensity beams, achieving good efficiency and excellent time resolution with a compact setup. Over this time the technique has evolved to cope with the challenge of measuring lifetimes of complex level schemes of increasingly exotic nuclei populated in β decay. The ISOLDE facility provides unsurpassed opportunities to study many regions of the nuclide chart. The physics case encompasses topics of interest across the nuclide chart, including the evolution of shell structure around neutron shell and subshell closures such as N=20, N=40 and N=50, shape coexistence, and octupole correlations in heavy nuclei. The recently commissioned ISOLDE decay station provides enhanced capabilities that will be fully exploited with the increased beam intensities available at the upcoming HIE-ISOLDE facility.
