Isomer Spectroscopy Near 132Sn -- First Observation of Excited States in 130Cd
Abstract
The isomer spectroscopy on nuclei in vicinity of the doubly-magic 132Sn was performed with use of the RISING array at the GSI Darmstadt. Two reactions were used to produce nuclei in this region: the fragmentation of 136Xe beam at 750 A·MeV and the fission of 238U beam at 650 A·MeV. Decays of about 20 isomeric states have been detected. Here we report in more detail on the observation of the 8+, π(g9/2)-2 isomer in 130Cd. Comparison to shell model predictions reveals good agreement and no indication of the N = 82 shell quenching.
