Excitation functions for proton elastic scattering and inelastic scattering to the 2.615-MeV (3~), 3.198-MeV (5-), 3.475-MeV (4~), 3.709-MeV (5~), 4.36-MeV, 4.48-MeV, and 4.69-MeV states in 208 Pb were measured at laboratory angles of 90°, 125°, 150°, and 170°. The beam energy was varied in 25-keV steps between 14.2 and 18.2 MeV. In this range of bombarding energies, the isobaric analogs of the g 9 /2, in/2, d b/2 , S1/2, g7/2, and d 9 /2 single-neutron states of 209 Pb were observed. The elastic-scattering cross sections have been analyzed to yield the parameters of the g 9/2 , d 5/2 , Si /2 , gy 2 , and d d/2 resonances. A simple interpretation of the decay of these resonances into the inelastic proton channels is offered, and the particle-hole structure of the excited states of 208 Pb is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
