Abstract: An (n, n'y) coincidence method was used to determine the neutron spin-flip probability in inelastic scattering. The experimental method consists of neutron time-of-flight and neutron-y coincidence technique with the deexcitation y ray detected perpendicular to the neutron scattering plane. The angular distribution of the spin-flip probability for the first Jπ =2+ excitation in carbon has been determined at an energy of 7.48 MeV. The neutron spin-flip results were found to be similar to the proton spin-flip results in this energy region. The experimental results were compared to the predictions of an antisymmetrized distorted-wave calculation which did not provide good fits to the spin-flip data. The spin-flip predictions were sensitive to the optical-model parameters and were dominated by spin-orbit distortion in the elastic channels. The mechanism of core polarization dominated the inelastic amplitudes, masking the effects of the effective interaction on the extracore nucleons.
