摘要：

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