An Analysis of Inelastic Scattering to the 2+ State in 54Fe at 1·409 MeV

Abstract

The differential cross section, spin-flip probability amplitude, and asymmetry for the inelastic scattering of19·6 MeV protons to the 2+ state in 54Feat 1·409 MeV are analysed. The antisymmetrized distorted wave approximation is used to evaluate the scattering amplitudes in which the reaction mechanism is represented by a generalized core polarization model. Good fits are obtained to the differential cross section and spin-flip probability data. The exchange core polarization contributions are shown to be essential to obtain such fits. However, the asymmetry data cannot be fitted simultaneously, and this failure demonstrates the limitations of the current collective model representation of the core polarization process
