Abstract
In this work, we simultaneously reanalyzed the differential elastic scattering crosssections (d sigma/d Omega) and the vector analyzing power (A(y)) of p + He-6 elastic scattering. This analysis was performed using the folded optical model for both real central and spin-orbit (SO) potentials, respectively. For the imaginary central, we used the usual Woods-Saxon (WS) form. Three different model density distributions are used to calculate the potential. We aimed to examine the applicability of the microscopically derived SO potential and the structure effect of He-6 nucleus. The presence of the A(y) experimental data of p + He-6 makes it interesting for this study. Our calculations showed that the three densities gave similar predictions for the cross-sections data. The three microscopic SO potentials calculations of A(y) are not in a good agreement with the experimental data. We concluded that the SO formalism in its current form needs more investigations for exotic halo nuclei.
