Nuclear structure of 96,98Mo: Shape coexistence and mixed-symmetry states

“…The angular correlation analysis of the 1190-849 keV γγ cascade suggests a spin for the state with either J 2818 = 4, 5, 6, but the spin assignment J 2818 = 5, 6, assuming only dipole and quadrupole transitions, can be ruled out due to the depopulating 1320.9 (5) keV transition to the J π = 2 + state reported in Ref. [29]. − − → 4 cascade the spin of this state could be limited to J = 6, 7.…”

“…However the relative γ intensity of the 241.36 (20) keV transition seems to be overestimated in Ref. [29], which might originate from a doublet with a 241.33 keV transition depopulating a state at 1869.64 (6) keV and which cannot be distinguished in the singles spectrum used in Ref. [29].…”

“…First, some states conflicting with previous data in 96 Mo and 98 Mo are discussed, followed by tables 1 and 2 with all experimental results. − − → 2 + 1 )=−1.05 +9 −10 , −0.6 (5), −6.9 +12 −21 , exist, where the first value was measured in a (n,γ) [29] experiment and the latter two originate from Ref. [5].…”

“…In order to determine the E2/M 1 mixing ratio, the two peaks at 847.68 (12) keV and 849.99 (9) (4 + 1 − → 2 + 1 ) keV have to be discriminated, which is impossible for NaI(Tl) detectors employed in Ref. [29] but possible in this experiment due to the superior resolution of the HPGe detectors. exp.…”

“…[29], which might originate from a doublet with a 241.33 keV transition depopulating a state at 1869.64 (6) keV and which cannot be distinguished in the singles spectrum used in Ref. [29]. The coincidence technique employed in this work allows to determine the branching ratio and avoids any contribution of the contaminating 241.33 keV transition.…”
