Excited states in the nucleus Sb-133, populated in spontaneous fission of C
m-248, were studied with EUROGAM2. Medium-spin structure, described as the
nu(f(7/2)h(11/2)(-1)) multiplet of the Sn-132 core coupled to the odd proto
n in the g(7/2) orbital, has been identified in this nucleus. Levels corres
ponding to the octupole excitations of the Sb-132 core were also identified
. Some uncertainities concerning isomeric decays in Sb-133, observed in pre
vious works, have been resolved.
