Neutron-induced gamma-ray production in /sup 208/Pb for incident-neutron energies between 4. 9 and 8. 0 MeV and in /sup 209/Bi for an incident-neutron energy of 5. 4 MeV
Interactions of neutrons with /sup 208/Pb have been studied by measuring photon production cross sections. Gamma-ray spectra were obtained at incident-neutron energies of 4.9, 5.4, 6.4, 6.95, 7.45, and 8.0 MeV with a gamma-ray detector system utilizing a 48-cm/sup 3/ Ge(Li) detector. Nearly monoenergetic neutrons were obtained from the D(d,n) reaction using deuterons obtained from the (pulsed) Oak Ridge National Laboratory 5-MV Van de Graaff accelerator. Time-of-flight was used to discriminate against pulses due to neutrons and background radiation. Extracted differential and total inelastic cross sections have been compared with previous measurements and with data from the ENDF/B evaluation with generally satisfactory results. New information on the level structure of /sup 208/Pb is reported. Data were also obtained at E/sub n/ = 5.4 MeV for a sample of natural bismuth, and new information on the level structure of /sup 209/Bi was obtained. Differential gamma-ray production cross sections were obtained, and the total inelastic cross section at E/sub n/ = 5.4 MeV was deduced from these data.
