Proton Particle-Hole States inPb208

The structure of ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ has been investigated using the ${}_{}{}^{209}{}_{}{}^{}\mathrm{Bi}(d, {}_{}{}^3{}_{}{}^{}\mathrm{He}){}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ reaction at 50 MeV. Angular distributions have been measured from 10-50° lab for 15 levels in ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$. These states in ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ are considered to be populated through their [$1h_{\frac{9}{2}}$, ${\mathrm{}\left(\mathrm{nlj}\right)\mathrm{}}^{-1\mathrm{}}$] proton particle-hole components. Spectroscopic factors have been extracted for each state and compared with those predicted by a recent random-phase-approximation calculation of Kuo and Brown. Generally good agreement between theory and experiment results.
