Spin-flip probability in the inelastic scattering of 15--40 MeV protons on light nuclei
Spin-flip probability angular distributions for proton scattering from the 2/sup +//sub 1/ level of /sup 24/Mg have been determined between 25/sup 0/ and 165/sup 0/ (in steps of 10/sup 0/) at 15 incident energies between 14.5 and 35.5 MeV and, to obtain a more detailed energy dependence at backward angles, spin-flip probabilities have also been measured between 115/sup 0/ and 165/sup 0/ at 10 additional energies. In order to extend the study of spin-flip probabilities also to other nuclei and to complement previous angular distributions, further backward angle data have been taken at 13 energies for /sup 32/S and near 40 MeV for /sup 12/C and /sup 28/Si. The experimental results have been compared with coupled-channel calculations based on the rotational model and, for /sup 24/Mg, also with the predictions of microscopic antisymmetrized distorted waves calculations including two-step contributions. The collective analysis proves that spin-flip probabilities are particularly sensitive to the sign of the quadrupole deformation.
