| Abstract: | Differential cross sections and analyzing powers were measured for inelastic scattering of 160 MeV protons to the 48Ca 10.24 MeV, 1+ state. DWIA calculations with shell-model wave functions which fit inelastic electron scattering form factors predict too much cross section at small q and too little at large q for inelastic proton scattering. These results are consistent with the q-dependent modification of magnetic transitions anticipated from mesonic effects such as virtual Δ(1232)-hole excitations. |
