摘要：

Measurements of the spin-flip probability Snn for inclusive inelastic proton scattering around 300 MeV from nuclei between 12C and 90Zr show that an enhanced spin response near 40 MeV excitation at q ∼ 100 MeV/c is a general feature of nuclear structure. Data for 40Ca at 800 MeV confirm that the enhancement is not a peculiarity of 300 MeV scattering. In addition, measurements in 44Ca up to 75 MeV show that the enhancement cannot be attributed solely to a relatively narrow resonance. Continuum RPA calculations suggest that the enhancement is due to the exhaustion of most S = 0 strength at lower energy and a shift of S = 1 strength to higher energy. © 1990.
