Abstract
A careful examination of photon and electron spectra from cyclotron- produced mixtures of light terbium isotopes led to the identification of a new isotope, Tb/sup 152/ with an 18.5-hr half life. The 344.1-kev transition from first excited state to ground in daughter Gd/sup 152/ was identified and shown to be identical in energy to a transition associated with the beta decay of 9.3-hr Eu/sup 152m/ to the same daughter nucleus. Gamma transitions of 180 and 265 kev are also assigned to the decay of Tb/sup 152/ (auth)
