Inelastic proton scattering via isobaric analog resonances allows derivation of rather complete information about neutron particle-hole states. We applied this method to the doubly-magic nucleus {sup 208}Pb by measuring angular distributions of the reaction {sup 208}Pb(p,p{sup '}) on top of the isobaric analog resonances in {sup 209}Bi with the Q3D magnetic spectrograph at Muenchen. We identify the six states of the i{sub 11/2}f{sub 5/2} multiplet and the four states of the i{sub 11/2}p{sub 3/2} multiplet in the energy range 4.6 MeV<E{sub x}<5.3 MeV. Firm spin assignments for the 10 states are given, most of them new. Additional measurements of the reaction {sup 207}Pb(d,p) confirm the assignments. A new state at E{sub x}=5239 keV has a dominant proton particle-hole structure with spin 4{sup -}.
