The total gamma-decay probability, the ground-state gamma branching ratio, and the branching ratios to a number of low-lying states as a function of excitation energy have been determined in /sup 208/Pb to approximately 15 MeV. The total yield of ground-state E2 gamma radiation in /sup 208/Pb can only be understood if decay of compound states is considered. Other observations in /sup 208/Pb include the absence of a significant branch from the giant quadrupole resonance (GQR) to the low-lying collective states at 2.6 MeV and 4.08 MeV, and a strong branch to a 3/sup -/ state at 4.97 MeV. 20 refs., 6 figs., 1 tab.
