Elastic photon scattering in 208Pb and 206Pb
Creators
Description
Average elastic photon scattering cross sections were measured for 208Pb and 206Pb between 9.5 MeV and 12.0 MeV. The results indicate that there is a significant amount of fine structure in the photoabsorption cross section in 208Pb in this energy region; but that 206Pb has little or no fine structure. Three concentrations of strength in 208Pb at 10.04, 10.60, and 11.27 MeV were found to be mainly dipole. This result is in disagreement with recent inelastic electron scattering results which claim that this strength is E2. Finally, the parity of the 7.06 MeV level in 208Pb was measured with plane-polarized photons and found to be J/sup π/ = 1-. This result contradicts an earlier, tentative assignment of J/sup π/ = 1+, which implied that the 7.06 level was an important part of the giant magnetic dipole resonance in 208Pb
