Beta-decay of $^{122}$Ag and structure of $^{122}$Cd

ORAL

Abstract

The structures of even-even Cd nuclei are considered to be an important testing ground for vibrational states coupled to intruder states with rotational degrees of freedom. In addition, there may be up to 3 isomeric states in $^{122}$Ag. Two of them are very similar in their adopted values for lifetime. We produced a $^{122}$Ag nucleus via proton induced fission of $^{238}$U. Subsequent decay of $^{122}$Ag to $^{122}$Cd is investigated at the Low-energy RIB Spectroscopy Station (LeRIBSS) at the HRIBF. Many new levels and new gamma transitions in $^{122}$Cd were observed. The parent half-life was also observed. The structure of this isotope will be discussed.
