Collective and noncollective states in 116 Cd studied via the β decays of 116 Ag m1,m2,gs

We have reinvestigated the β decay of the three isomers of 116 Ag at the Holifield Radioactive Ion Beam Facility (HRIBF). Through the use of half-life information, we have been able to construct individual decay schemes for each isomer and correct what was a puzzling inconsistency with the published data, namely the β feeding of 2 + states by a 5 + isomer. Our results indicate that the feeding of these levels arises from a 3 + isomer in 116 Ag. A total of 271 γ-ray transitions (159 new) were assigned to 148 levels (94 new) from the β decay of 116 Ag m1,m2,gs . Significant deviations are observed from IBM-2 calculations for the decay of the 0 + and 2 + members of the previously assigned three-phonon quintuplet. Candidate states for the quadrupole-octupole quintuplet states and πg 9/2 -πp 1/2 , πg 9/2 -πp 3/2 , νh 11/2 -νs 1/2 , νh 11/2 -νd 3/2 , and νh 11/2 -νd 5/2 broken-pair states are assigned.
