Description

The depolarization parameter D in proton-13C elastic scattering at 72 MeV has been measured with an accuracy of 0.003--0.004 per data point. D was found to deviate from unity by ∼0.02 around 65 degree, which is unambiguous evidence for a nucleon-nucleus spin-spin interaction. The data are well described by a microscopic calculation as well as by a phenomenological optical-model potential, which includes a real spherical spin-spin potential of strength Vss=0.7±0.1 MeV
