Collective and Non-Collective States in 116Cd Studied via the Beta-Decays of 116Agm1,m2,gs

We have re-investigated the beta decayof 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 schemesfor each isomer, and correct what was a puzzling inconsistency with the published data, namely the beta 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 gamma-ray transitions (159 new) were assigned to 148 levels (94 new) from the beta-decayof $$^{116m1,m2,gs}$$Ag. Significant deviations are observed from expected U(5) symmetry in the 0$^+$ and 2$^+$ members of the previously assigned three-phonon quintuplet. Candidate states for the quadrupole-octupole quintupletstates and $$\pi$$g$$_{9/2}-\pi$$p$$_{1/2}$$, $$\pi$$g$$_{9/2}-\pi$$p$$_{3/2}$$, $$\nu$$h$$_{11/2}-\nu$$s$$_{1/2}$$, $$\nu$$h$$_{11/2}-\nu$$d$$_{3/2}$$, and $$\nu$$h$$_{11/2}-\nu$$d$$_{5/2}$$ broken pair states are assigned.
