Extended yrast level schemes in $^{121,123}$Cd

ORAL

Abstract

New level structures for $^{121,123}$Cd will be presented that were determined in the study of the $^{64}$Ni- and $^{76}$Ge-induced fission of $^{238}$U at Gammasphere [1]. A number of transitions were previously observed by Hwang et al. from which yrast levels were identified with maximum proposed spins of 27/2- and 23/2- in $^{121,123}$Cd, respectively [2]. If the additional transitions have stretched E2 multipolarity, these level structures would be extended to 31/2- at 4083 keV, and 35/2- at 5365 keV in $^{121,123}$Cd, respectively. These level sequences will be compared to existing levels in the lighter odd-mass Cd nuclei and the isomeric structures and calculations in the heavier odd-mass Cd nuclei.\\[4pt] [1] C. J. Chiara, I.
