Abstract

Newly observed decay schemes of the nuclei ${}^{137}{Sb}$ and ${}^{138}{Sb}$ are reported. The neutron-rich Sb isotopes were produced by the in-flight fragmentation of a ${}^{238}U$ primary beam with an energy of 345 MeV/nucleon. Several new excited states of ${}^{137}{Te}$ with tentatively assigned spin-parities of $(5 / 2^{-})$ , $(9 / 2^{-})$ , and $(7 / 2)$ have been established which play an important role in the evolution of neutron levels beyond $N = 82$ . The study of the $β$ decay of ${}^{138}{Sb}$ led to a considerable extension of the level scheme of ${}^{138}{Te}$ including the identification of several nonyrast states. The structure of ${}^{137}{Te}$ and ${}^{138}{Te}$ is discussed on the basis of large-scale shell-model calculations performed using two different effective interactions.
