High-spin level structure inMo94,95

“…The main discrepancies concern the spin and parity assignments for some important energy levels. First, the weak 386-keV transition is found to be quadrupole rather than dipole [9], leading to the assignment of (19/2 + ) for the level at 2619 keV. As mentioned in the previous paragraph, the level spacing and ordering for the ( 666-, 771-, and 1070-keV transitions have been determined to be quadrupole in this experiment, which is consistent with Ref.…”

“…During the course of this investigation, Chatterjee et al reported a new level scheme of 95 Mo [9] in which the spin and parity assignments for some interesting energy levels were different from our result. In addition, we have carried out shell-model calculations up to high-spin states to understand the high-spin level structures of 94 Mo and 95 Mo.…”

“…The ADO ratio for the 1445-keV γ ray has been checked with care, and it is found to be a dipole transition in agreement with Ref. [9]. This γ ray is assigned as an E1, (27/2 − ) → (25/2 + ) transition, which provides in turn a supplementary argument for the observation of the 386-keV, (19/2 + ) → (15/2 + ) transition.…”

“…Most of the γ rays reported in the literature [4][5][6][7]9] have been observed in this experiment. The γ -ray coincidence relationships and their ADO ratios have been analyzed with care, leading to the establishment of the revised level schemes for 94,94 Mo that significantly differ from the previous work.…”

“…The above-mentioned γ rays were found to be in coincidence with the 385. 95 Mo is not fully consistent with the recent work of Chatterjee et al [9]. The main discrepancies concern the spin and parity assignments for some important energy levels.…”
