Observation of Isomeric Decays in the r-Process Waiting-Point Nucleus 130Cd
(2007) In Physical Review Letters 99(13).- Abstract
- The gamma decay of excited states in the waiting-point nucleus 130Cd82 has been observed for the first time. An 8+ two-quasiparticle isomer has been populated both in the fragmentation of a 136Xe beam as well as in projectile fission of 238U, making 130Cd 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 98Cd50 to 130Cd82 and reveal, in comparison with 76Ni48 one major proton shell below, an apparently abnormal scaling of nuclear two-body interactions.
