Spin-flip probability in the inelastic scattering of 14.2 MeV neutrons from the 2.23 MeV state of 32S
The spin-flip probability for 14.2 MeV neutrons scattered inelastically from the Q = -2.23 MeV first excited state of sulphur has been measured at scattering angles between 40° and 160° using a γ-correlated neutron time-of-flight method. The results of the measurements were compared to the predictions of a coupled-channels code. A vibrator model with a quadrupole deformation parameter β2 of 0.37 was used, and searches on the optical model potential parameters were made. The calculations were able to account for elastic and inelastic scattering data, but did not provide a satisfactory fit to the spin-flip data.
