摘要: Proton scattering on 208Pb via isobaric analog resonances (IARs) in 209Bi generates neutron particle-hole configurations excited states of . The spin and parity the particle correspond to resonance. We performed experiments (p, p’) reaction all known with Q3D magnetic spectrograph Munchen. observed more than 130 levels range excitation energies Ex < 6.4 MeV. In proton decay d5/2 resonance, 29 have cross-sections larger 5% maximum cross-section any level. Six 4.6 5.2 MeV spins major \(\ensuremath \nu(d_{5/2}^{+1} p_{1/2}^{-1})\) strength. 5.7 contain most p_{3/2}^{-1})\) At least one level originates from an unresolved doublet. Among a component, only 1- 3- are firmly identified. comparison previous data taken semiconductor detectors reveals details structure at 18
