Microscopic spin-orbit potential for p +6He elastic scattering
Abstract
In this work, we simultaneously reanalyzed the differential elastic scattering cross-sections (dσ/dΩ) and the vector analyzing power (Ay) of p +6He 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 6He nucleus. The presence of the Ay experimental data of p +6He 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 Ay 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.
