In-beam γ -ray spectroscopy of 131 Xe was carried out to study the structure of the intruder νh 11/2 band. Excited states were populated via an α-induced fusion-evaporation reaction at E α = 38 MeV. Inspection of γ γ -coincidence data resulted in the identification of a new rotational sequence. Based on the systematics of excitation energy, assigned spin-parity, decay pattern, and the electromagnetic character of the interband I = 1 γ transitions, this sequence is proposed as the unfavored signature partner of the νh 11/2 band. The structure of this band is further illuminated in the light of the triaxial particle rotor model (TPRM). The possibility of wobbling excitation in N = 77 Xe-Ba-Ce isotones was explored in a systematic manner.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
