The differential cross section, spin-flip probability amplitude and asymmetry for the in-elastic scattering of 19.6 MeV protons to the first 2+ state in 54Fe are analyzed using an antisymmetrized distorted-wave approximation. Core-polarization effects dominate all the analyses. These yield results similar to the collective-model analyses. The contributions of the microscopic components are small but show significant effects. The exchange terms give spin-flip probabilities that peak in regions where the data has a peak and the collective-model analyses do not. The necessity of including exchange amplitudes either in a much extended shell-model description of the target states or through the e..
