Abstract
The nuclei I131 and I133 have been populated in multinucleon transfer reactions between Xe136 ions and various targets, and their structure has been investigated by time-correlated γ-ray coincidence spectroscopy and the measurement of γ-ray angular correlations. A 19/2- isomer at 1918 keV, with a half-life of 24(1) μs, has been identified in I131, as well as nanosecond isomers with Jπ=23/2+ in both isotopes. A T1/2=25(3) ns isomer at 4308 keV in I131 is suggested to have Jπ=(31/2-,33/2-) and is primarily attributed to the coupling of an odd proton in the d5/2 or g7/2 orbit with the (π2)0+(νh11/2-3d3/2-1)15- configuration in Te130 responsible for the 15- isomer in that nucleus. The observed level properties are compared with predictions of a shell-model calculation.
