Abstract

Gamma rays decaying from the excited states of the proton-unbound [Formula Presented] were observed for the first time in an experiment using the [Formula Presented] reaction. These γ rays were identified by correlating prompt γ radiations at the target position with [Formula Presented] proton radioactivities at the focal plane of a recoil mass separator. Systematic data on [Formula Presented] isotones suggest a possible isomeric level at high spin in [Formula Presented] Our measurement was unable to observe such an isomer, but provided an upper limit on its half-life. The observed γ rays in [Formula Presented] can be interpreted in terms of two possible level structures.
