Depolarization in proton-6Li elastic scattering
1994
Abstract We have measured the differential cross section dσ/dΩ, the analyzing power A y and the depolarization parameter D for p- 6 Li elastic scattering at 72 MeV. The spin/isospin character of this transition and the large spinflip effects observed make p- 6 Li 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.
