Sources of /sup 235/Th and /sup 235/Pa were prepared by medium energy neutron and proton irradiations of uranium followed by radiochemical separations. Gamma-ray spectroscopy showed 13 new ..gamma.. rays in the decay of /sup 235/Th. Its half-life is 7.3 +- 0.1 min, and that of /sup 235/Pa is 24.6 +- 0.2 min. A partial decay scheme is proposed for /sup 235/Th, and a large anomalous retardation is reported in one branch of the /sup 235/Pa ..beta../sup -/ decay.
