New isomeric state in Ag116
A new isomer in Ag116 with a half-life of 20(1) s has been discovered through the use of conversion electron, β, and y spectroscopy of on-line mass-separated radioactivities at the Holifield Radioactive Ion Beam Facility at ORNL. The observed electron peaks at 22.5, 44.42, and 47.33 keV were interpreted as the K,L, and M conversion electron lines resulting from a 47.9-keV E3 transition associated with the decay of a second isomeric level in Ag116. A new level structure of Ag116 is proposed, with the levels identified as the 0- ground-state and isomers at 47.9 and 128.8 keV having spin/parities of 3+ and 6- respectively. © 2005 The American Physical Society.
