Analysing power for28Si(n,n0,1)28Si and sensitivity of spin-orbit potential parameters

Abstract
The analysing power Ay( theta ) for elastic and inelastic (2+, E*=1.78 MeV) neutron scattering from Si was measured at 14.1 MeV. The data were analysed together with published differential cross sections using the coupled-channels formalism. The parameters of the optical potential, especially for the spin-orbit part, could be definitely determined from the authors' accurate analysing power data.
