Abstract

The decay of Cs 138 to levels in the 82-neutron isotone Ba 138 was investigated with Ge(Li) and NaI(T1) γ detectors. On the basis of energy, intensity, and coincidence measurements a new decay scheme is proposed including 31 levels. States at 2090, 2415, 2779, 2931, 2991, 3164, 3352, 3442, 3647, 3861, 3880, 3935, 4081, and 4507 keV were not seen in earlier studies of the Cs 138 ground-state decay. Spin assignments were made for all levels. Our level scheme is compared with the results of recent decay and reaction experiments and with the predictions of shell-model calculations.
