Abstract

The spin-flip probability for scattering protons inelastically to produce the first excited 2+ states in C12 and S32 has been measured at proton energies of 15.9 and 17.5 MeV using the deexcitation γ rays emitted perpendicular to the scattering plane. The carbon results agree with previous measurements in the same proton energy region. The measured inelastic spin-flip probability on sulfur is higher than that reported for any other nucleus, exceeding a peak value of 0.5. A collective distorted-wave Born-approximation analysis employing the full Thomas spin-orbit interaction was carried out. Poor fits are obtained for the spin-flip-probability data when the depth and range of the spin-orbit optical potential are determined from elastic polarization data.
