Abstract
Excited states in the proton-unbound nucleus [Formula Presented] were populated using the [Formula Presented] reaction at a beam energy of 220 MeV. Gamma rays in [Formula Presented] were identified using the recoil-decay tagging technique. The analysis of proton-correlated [Formula Presented] coincidence data produced the yrast decay sequence in [Formula Presented], which can be tentatively assigned as built on the [Formula Presented] proton state based on systematic trends in the neighboring isotopes. This sequence is completely different from that reported previously. A comparison of the [Formula Presented] band [Formula Presented] with those in heavier iodines shows that [Formula Presented] continues the trend of decreasing quadrupole deformation with decreasing neutron number.
