Phenomenological and Microscopic Analysis of Elastic Scattering Reactions: 9Be+27Al New Results
Yusuf Sert,Rukiye Ye˘gin 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.66 No.5
In this study, elastic scattering of the 9Be+27Al system has been re-analyzed by using phenomenologicalmodel (WS) and microscopic double-folding model (DF) potentials within the frameworkof the optical model at different incident energies. In the phenomenological and double-foldingcalculations, we have used the new parameters to explain the 9Be+27Al reaction. The real potentialsin the double-folding calculations have been obtained by using the density distribution of the9Be projectile and the 27Al target. The imaginary potentials have been taken as the Woods-Saxonvolume. The imaginary radius rw and the imaginary diffusion parameter aw have been fixed to 1.1fm and 1.85 fm, respectively. We compare the phenomenological model results with the doublefoldingmodel ones as well as the experimental data. These comparisons provide information aboutthe similarities and the differences in the models used in the calculations. The cross sections, thevolume integrals and the χ2/N values have been obtained for seven energies. Additionally we haveshown a threshold anomaly for the 9Be+27Al system in the both calculations.
