Consistent dispersive optical-model analyses for n+{sup 209}Bi and n+{sup 208}Pb from -20 to +80 MeV
- and others
Complementary databases were constructed from published and some new measurements of {sigma}({theta}), Ay({theta}) and {sigma}{sub T} for n+{sup 208}Pb and n+{sup 209}Bi covering the energy range 1.0 to 80 MeV. A dispersive optical-model analysis was performed for both scattering systems while constraining many of the parameters to be identical. A good representation of the data is obtained with conventional geometry and spin-orbit parameters. The {sup 208}Pb model predicts quite well measured energies of single-particle and single-hole bound states. Occupation probabilities are calculated. A fully constrained model is presented in which the only differences between the two systems are the Fermi energy and the usual isospin term. This latter model represents all the data well.
