Differential cross-section data of elastic scattering for p +9Be below a proton incident energy of 30MeV 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.

30MeV以下的p+9Be弹性散射：光学模型分析和数据归一化
