Abstract [en]

A recoil-beta-tagging experiment has been performed to study the excited T = 0 and T = 1 states in the odd-odd N = Z nucleus Ag-94, populated via the( 40)Ca(Ni-58,1p3n)Ag-94 reaction. The experiment was conducted using the MARA recoil separator and JUROGAM3 array at the Accelerator Laboratory of the University of Jyv & auml;skyl & auml;. Through correlating fast, high-energy beta decays at the MARA focal plane with prompt gamma rays emitted at the reaction target, a number of transitions between excited states in Ag-94 have been identified. The timing characteristics of these transitions confirm that they fall within decay sequences that feed the short-lived T = 1 ground state of Ag-94. The transitions are proposed to proceed within and between the sets of states with T = 0 and T = 1. Possible correspondence between some of these transitions from analog states in( 94)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 T = 0 and T = 1 states and to allow a theoretical set of Coulomb energy differences to be calculated for the A = 94 T = 1 analog states.
