Abstract

Using the Pb-208(p, p') reaction via isobaric analog resonances in Bi-209, a dozen states in the doubly magic nucleus Pb-208 with major strength of the neutron particle-hole configuration nu(d(5/2)(+1)p(3/2)(-1)) are investigated. Among them, two doublets at E-x = 5.81, 6.01 MeV are resolved by comparing the mean cross sections on the d(5/2) resonance. The 5.81 MeV doublet consists of two states with major configuration nu(d(5/2)(+1)p(3/2)(-1)) and spins 2(-) and 3(-); the 2(-) state is newly identified. The distance between the two states is 0.4 +/- 0.2 keV. The 6.01 MeV doublet consists of a 4(-) state with dominant configuration.(d(5/2)(+1)p(3/2)(-1)) and a 3-state with a small admixture of nu(d(5/2)(+1)p(3/2)(-1)). The distance between the two states is 1.8 +/- 0.3 keV. The 5886 state has been newly assigned the spin of 4(-). The spins of seven more states are verified. Almost the complete nu(d(5/2)(+1)p(3/2)(-1)) strength is identified in these 12 states. The center of gravity for the configuration nu(d(5/2)(+1)p(1/2)(-1)) and nu(d(5/2)(+1)p(3/2)(-1)) is in line with the predictions by the shell model without residual interaction to within 10 keV.
