Abstract
Prompt -ray cascades in fission product nuclei near Sn have been studied at Eurogam II using a Cm source. Cross coincidences observed between rays from complementary light and heavy fission fragments were vital for isotopic assignments. Yrast states in the isotones Sb, Te, and I are reported. The interpretation of the level schemes is based mainly on results of shell model calculations using empirical proton-proton interaction energies from Te, and proton-neutron interactions estimated from the well-known Bi level spectrum.
