102Ag:: In-beam gamma ray spectroscopy

Abstract

Gamma rays associated with the decay of states in Ag-102 nucleus have been identified, sixty-four of them for the first time following the reaction Cr-50 (Fe-56, 3pn) Ag-102 at a mean energy of 195 MeV. Identification was made using an array of nine, escape-suppressed Ge detectors coupled to a Daresbury Recoil Separator. Excited states in Ag-102 were identified using recoil-gamma and gamma-gamma. coincidences. From the intensity balance and the coincidence data, a new set of levels was identified which may be interpreted as the reminiscent of three quasiparticle bands in neighboring odd-mass nuclei and similar to a four quasi-particle band observed in Ag-106.
