19/2 super(+) isomer of super(125)Cd and realistic shell-model calculations of neutron-rich Cd isotopes

The decay of a T sub([1/2]) = 19(3) mu s isomeric state from super(125)Cd has been observed using gamma -ray spectroscopy at the Lohengrin mass spectrometer of the Institut Laue-Langevin, Grenoble. Two coincident gamma rays were observed to be emitted from the decay of this isomeric state, contradic...

Description
Summary:The decay of a T sub([1/2]) = 19(3) mu s isomeric state from super(125)Cd has been observed using gamma -ray spectroscopy at the Lohengrin mass spectrometer of the Institut Laue-Langevin, Grenoble. Two coincident gamma rays were observed to be emitted from the decay of this isomeric state, contradicting recently published data on this nucleus. Realistic shell-model calculations have been performed to interpret the decay scheme, allowing a spin and parity of 19/2 super(+) to be assigned to the isomeric state. All configurations contributing to this isomeric state have amplitudes less than 7 %. Experimental data have recently been published on the decays of mu s isomeric states in super(127, 128, 130)Cd. Realistic shell-model calculations for these nuclei are presented which reproduce the known experimental decay schemes reasonably well.
