The inelastic scattering of 162 MeV and to states in was studied. Isoscalar and isovector structure amplitudes were extracted for each state. The summed isoscalar strength corresponds to only 11% of that predicted in an calculation, while 38% of the isovector strength is observed. This is similar to the quenching of strength observed in lighter nuclei and demonstrates that the strong quenching of the isoscalar spin-flip strength persists in the shell.
