The neutron decay of the giant multipole resonance region between 9 to 15 MeV in /sup 208/Pb has been studied. The giant resonances were excited by inelastic scattering of /sup 17/O at 380 MeV. Neutrons from /sup 208/Pb and ..gamma.. rays from /sup 207/Pb were detected in the ORNL Spin Spectrometer and the /sup 17/O in ..delta..E-E silicon detector telescopes. The neutron branching ratios for the decay to the ground state and to the low lying excited states of /sup 207/Pb were measured as a function of the excitation energy of /sup 208/Pb and compared to Hauser-Feshbach calculations. Evidence for non statistical neutron decay to selected single-hole states, and to hole-surface vibration and hole-pairing vibration coupled states was found. 18 refs., 1 tab., 5 figs.
