Abstract

The radioactivity of UY ( ${Th}_{231}$ ) has been re-investigated. Samples were prepared by growth from $U_{235}$ largely freed of $U_{238}$ , and absorption, decay, and coincidence experiments were run. The presence of the 210-kev beta-ray was re-confirmed, and a 35-kev gamma-ray 82 percent converted in the $L$ shell was discovered. The half-life of UY was determined as 25.5 hours.
