Abstract
We have determined 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 in 208Pb to ~ 15 MeV. The total yield of ground-state E2 gamma radiation in 208Pb can only be understood if decay of compound states is considered. Other observations in 208Pb 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- state at 4.97 MeV.
