Collective and noncollective states in Cd116 studied via the β decays of Ag116m1,m2,gs
We have reinvestigated the β decay of the three isomers of Ag116 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 Ag116. A total of 271γ-ray transitions (159 new) were assigned to 148 levels (94 new) from the β decay of Ag116m1,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 πg9/2-πp1/2, πg9/2-πp3/2, νh11/2-νs1/2, νh11/2-νd3/2, and νh11/2-νd5/2 broken-pair states are assigned. © 2009 The American Physical Society.
