Abstract
Gamma rays in the ${}^{132}\mathrm{Sb}$ and ${}^{133}\mathrm{Te}N=81$ isotones near doubly magic ${}^{132}\mathrm{Sn}$ have been studied at Gammasphere using a ${}^{248}\mathrm{Cm}$ fission source. Previously unknown yrast cascades in the two nuclei were identified in cross coincidence with known \ensuremath{\gamma} rays from complementary Rh and Ru fission fragments. The ${}^{132}\mathrm{Sb}$ levels are explained as proton-neutron hole states as well as core excited states of $2p\ensuremath{-}2h$ character, while the interpretation of the ${}^{133}\mathrm{Te}$ level scheme is mainly based on results of shell model calculations using empirical proton-proton interaction energies from ${}^{134}\mathrm{Te}$ together with estimated proton-neutron hole interactions.
