摘要：

We have measured the differential cross section dsigma/dOMEGA, the analyzing power A(y) and the depolarization parameter D for p-Li-6 elastic scattering at 72 MeV The spin/isospin character of this transition and the large spinflip effects observed make p-Li-6 elastic scattering a good case to study the isoscalar spinflip component of the effective force. The data were fitted by a conventional optical-model potential which included a real, spherical spin-spin potential with surface form factor and V(SS) = 5.3 +/- 1.0 MeV. A qualitative description of the data was also achieved with a ''semi-microscopic'' folding calculation based on the density-dependent Paris effective force, shell-model wave functions and a phenomenological optical-model potential.
