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.
