“…[21]. In our work, this is inferred to be 1.6(3) compared with the previously measured value of 1.9(4) [21] and a theoretical value of 1.61 [43]. On this basis, the 81-keV transition in 86 Tc is assigned to be of a stretched-E2 multipolarity, leading to a spin/parity assignment of (6 + ) for the isomeric state.…”

“…Assuming a dipole transition from the isomeric state, the measured half-life is much greater than the calculated partial half-life shown in Table IV [43]. As discussed in Ref.…”

“…84 41 Nb 43 The first γ -ray transitions assigned to 84 Nb were identified by Gross et al [42], where two band structures were observed but were not fitted into a joint level scheme. A further in-beam study by Mȃrginean et al [45] enabled the construction of a comprehensive level scheme at low excitation energy.…”

“…In addition, our work finds that a state at 305 keV reported by Mȃrginean et al [45] is isomeric. Delayed γ -ray spectra produced from gating on ions Table V along with calculated internal conversion coefficients and single-particle Weisskopf estimates [43]. Because of the short half-life of the isomeric states and the low energy of the transitions in this nucleus, the intensity measured for each γ ray in this case is especially sensitive to the chosen start channel of the time gate.…”

“…The intensities have been normalized to the intensity of the 114-keV transition. Also shown are calculated internal conversion coefficients [43] and the single-particle Weisskopf estimate of the assigned multipolarity [43]. scheme of Fig.…”
