[en] Exclusive p-p correlations from the ⁵⁸Ni + ⁵⁸Ni reaction have been measured at an incident energy of 850 MeV. The enhancement in the p-p correlation function for small Δp is satisfactorily explained by p-p final-state interaction effects. The observed enhancement is found to depend on the relative angle between the fragment and p-p c.m. velocities. The observed dependence of the p-p coincidence yield on the orientation of Δp with respect to the plane spanned by the fragment and p-p c.m. velocities is attributed to angular momentum effects.
