Abstract
The gamma rays following the decay of208Tl have been studied using a separated208Tl-source and a Ge(Li)-detector. A decay scheme is proposed, with levels in208Pb at 3,920, 4,126 and 4,180 keV in addition to previously well-established levels. No support was found forΒ-branching to levels above 4.2 MeV.
