Abstract
By analysis of fission product $\gamma$ -ray data measured at Eurogam II using a ²⁴⁸Cm source, yrast levels up to about 2 MeV in the N=84 three-particle nucleus ¹³⁵Sb have been identified. These levels are interpreted as ${\rm \pi g_{7/2}\nu f_{7/2}^{~2}}$ and ${\rm \pi g_{7/2}\nu f_{7/2}h_{9/2}}$ states with the help of shell model calculations using empirical nucleon-nucleon interactions.
