Optical Model Calculation

Optical-model analysis of the elastic scattering of 6.0- and 8.0-MeV 3He particles on 9Be is performed with and without spin–orbit coupling. Good agreements with data are obtained, indicating the applicability of the optical model in describing the elastic scattering of 3He particles from such light nuclei as 9Be. Inclusion of spin–orbit interaction is found to improve fits, especially at backward angles. Almost equally good results are obtained by volume or surface absorption, although surface absorption gives slightly better fits at 8.0 MeV. Parameters giving the optimum fits to the data are presented and several ambiguities in the potential are discussed.

Elastic scattering cross sections for the interaction of 100-MeV protons with 6Li, 7Li, 9Be, and 12C have been analyzed using the optical model. The experimental differential cross sections are reasonably reproduced. It has been found that no average set of geometrical parameters can provide a quantitative fit to the experimental data for all of these light nuclei; they must be treated individually, with optimum optical potential parameters fluctuating from one nucleus to another. Other features revealed in this analysis include: (1) the spin–orbit radius parameter is smaller than those of the real and imaginary parts of the potential, (2) surface and volume absorption potentials give equally good fit to the experimental results, (3) the radius parameters of the real and imaginary potentials differed from each other, and (4) the radius parameter of the real part of the potential is larger than those used for heavy nuclei.

Angular distributions of elastically scattered 3He on 16,17,18O at 14 MeV were measured. Optical model analysis of the data has been performed. In the case 16O case, a spin–orbit term is needed to provide better fits of the data at backward angles and this term allows a satisfactory calculation of the 16O(3He, α)15O reaction.

In this work, we simultaneously reanalyzed the differential elastic scattering cross-sections ([Formula: see text]) and the vector analyzing power ([Formula: see text]) of [Formula: see text]He 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 [Formula: see text] experimental data of [Formula: see text]He 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 [Formula: see text] 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.
