Measurements of the spin‐flip probability Snn for inclusive inelastic proton scattering around 300 MeV determine the relative ΔS=1/(ΔS=0+ΔS=1) response of the nucleus provided Snn is a ‘‘robust’’ observable. Recent data then give a general picture of the nuclear spin response up to about 40 MeV of excitation for momentum transfers up to about 200 MeV/c. Slab model calculations give qualitative agreement with much of the data; they explain the small values at high excitation. They do not explain the values approaching 90% for intermediate momentum transfers. RPA calculations which localize the S=0 strength at lower excitation energies, coupled with a shift in S=1 strength to higher excitations.
