Beta decay strengths from the decay of $^{116m1,m2,gs}$Ag

ORAL

Abstract

An inconsistency with the published data on the decay of a 5+ $^{116m}$Ag has been the non-zero beta feeding strength for the decay of 116Ag to low-lying levels with spins of 2 and 3 [1]. Recently [2], we have shown that 116Ag has a third isomer. Through the use of conversion electron and gamma spectroscopy, we were able to show that the ground state must be 0- rather than the previously assigned 2- [3]. This results in the three beta-decaying levels in 116Ag having J$^{pi}$ of 0-, 3+, and 6-. Our results indicate that the feeding of the levels in $^{116}$Cd with spins of 2 and 3 arise from the 3+ isomer in $^{116}$Ag, which is perfectly consistent with allowed beta transitions from the 3+ $^{116m1}$Ag isomer. In this talk, a discussion of the beta strengths of the three isomers as well as the levels in Cd will be presented. [1] Y. Wang, et al., Phys. Rev. C 64, 054315 (2001). [2] J. C.
