Excitation of Single Neutron Hole States inPb207by Inelastic Proton Scattering at 20.2 MeV

Differential cross sections for the excitation of the 0.570-, 0.894-, 1.633-, 2.33-, and 2.74-MeV states in ${\mathrm{Pb}}^{207}$ have been measured in inelastic proton scattering at 20.2 MeV. Analysis via the microscopic model indicates that core polarization is important in describing these presumed single-particle transitions.
