Gamma-ray cascades in the two- and three-valence-particle nuclei Sb-134 and Te-135 have been studied with Gammasphere using a Cm-248 spontaneous fissi on source. Isotopic assignments were based in part on coincidences with gam ma rays from complementary Rh and Ru fission partners. The Sb-134 and Te-13 5 level schemes have been considerably extended, with placement of many new high-energy gamma rays; delayed gamma -ray coincidences observed across a 0.51-mus yrast isomer in Te-135 were especially fruitful. The yrast level s pectra of both nuclei are interpreted using empirical nucleon-nucleon inter actions and compared with the known yrast excitations of their counterparts Bi-210 and Po-211.
