A new isomer in {sup 116}Ag with a half-life of 20(1) s has been discovered through the use of conversion electron, {beta}, and {gamma} 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 {sup 116}Ag. A new level structure of {sup 116}Ag is proposed, with the levels identified as the 0{sup -} ground-state and isomers at 47.9 and 128.8 keV having spin/parities of 3{sup +} and 6{sup -} respectively.
