Abstract

Levels in Ag104 and Ag102 were studied using mainly the Mo94(C12, pn) and the Y89(O16, 3n) reactions, respectively. A set of standard in-beam measurements involving relative excitation functions of γ rays, γγt coincidences, conversion electrons, angular distributions, and linear polarization of emitted γ rays have been performed. Excited states with spin values up to 17 and 14 are populated in Ag104 and Ag102, respectively. The experimental data are discussed in the framework of the axial plus two quasiparticle model and some simple rules have been deduced to interpret the behavior of odd-odd transitional nuclei at high angular momentum.
