Abstract

The γ decay of excited states in the waiting-point nucleus Cd82130 has been observed for the first time. An 8+ two-quasiparticle isomer has been populated both in the fragmentation of a Xe136 beam as well as in projectile fission of U238, making Cd130 the most neutron-rich N=82 isotone for which information about excited states is available. The results, interpreted using state-of-the-art nuclear shell-model calculations, show no evidence of an N=82 shell quenching at Z=48. They allow us to follow nuclear isomerism throughout a full major neutron shell from Cd5098 to Cd82130 and reveal, in comparison with Ni4876 one major proton shell below, an apparently abnormal scaling of nuclear two-body interactions.
