A recoil-beta-tagging experiment has been performed to study the excited 
and 
states in the odd–odd 
nucleus Ag, populated via the 
Ca(
Ni,1p3n)Ag reaction. The experiment was conducted using the MARA recoil separator and JUROGAM3 array at the Accelerator Laboratory of the University of Jyväskylä. Through correlating fast, high-energy beta decays at the MARA focal plane with prompt rays emitted at the reaction target, a number of transitions between excited states in Ag have been identified. The timing characteristics of these transitions confirm that they fall within decay sequences that feed the short-lived ground state of Ag. The transitions are proposed to proceed within and between the sets of states with and . Possible correspondence between some of these transitions from analog states in Pd has been discussed, and shell-model calculations including multipole and monopole electromagnetic effects have been presented, in order to enable predictions of the decay patterns between the and states and to allow a theoretical set of Coulomb energy differences to be calculated for the 
analog states.
