a Study of LEAD-206 by Inelastic Scattering of 35 Mev Protons.

Using high resolution techniques the inelastic scattering of 35 MeV protons by ('206)Pb have been measured. A resolution of 6 to 9 keV allowed identification of approximately 180 levels of ('206)Pb with excitation energies up to 6.8 MeV. Angular distributions of most of these states are measured. L-transfers and deformation parameters are determined by comparison of the measured angular distributions to collective model calculations. Strongly excited collective states are compared to analogous states in ('207)Pb and ('208)Pb and the overall distribution of inelastic strength in ('206)Pb is compared to ('208)Pb. Microscopic calculations of natural parity states are presented and allow a test of theoretical RPA and TDA wave functions. Unnatural parity states with well determined wave functions are also studied microscopically and permit an examination of the central and noncentral forces in the effective interaction.
