The p +9Be elastic scattering below 30MeV: Optical model analysis and data normalization

Differential cross-section data of elastic scattering for [Formula: see text]Be below a proton incident energy of 30[Formula: see text]MeV are evaluated by using two techniques. First, optical model analysis is performed and applied to the analyzing powers and reaction cross-sections to extract the optical potential parameters. Then, angular distributions of the differential cross-section are calculated with this potential and compared with the experimental data and normalization coefficients are extracted. Second, a consistent comparison between data sets with similar energies is considered in a minimization process to obtain another set of data normalization coefficients. The two techniques lead to similar normalized values for the existing data and consistently validate a body of low-energy data that can be safely used for further theoretical studies. Furthermore, the systematic behavior and energy dependence of the volume integral are determined as well as the energy dependence of the reaction cross-sections is predicted.

Optical Model Analysis of α + 40Ca at Elab=104 and 141.7 MeV

Optical model analysis of the elastic scattering analysis of α + 40Ca at Elab=104 and 141.7 MeV have been performed using the folding model approach of the nuclear reaction video (NRV) knowledge base code. The M3Y-type effective nucleon-nucleon interaction derived using the lowest order constrained variational (LOCV) approach for mass number A=40 was used to obtain the results. Elastic scattering differential cross section data were obtained for this system at two bombarding energies. The calculated differential cross sections are in good agreement with the experimental results and the anticipated mass dependence of the M3Y-type effective interaction improved the results at forward angles. This shows that, the mass dependence of the M3Y-type effective interaction in our results should be of value in the description of the scattering of other nuclear systems
