Global optical model potential for the weakly bound projectile Be9

Abstract

The global optical model potential for the $^{9}\mathrm{Be}$ projectile is developed by systematically studying the experimental data of elastic-scattering angular distributions and reaction cross sections from $^{24}\mathrm{Mg}$ to $^{209}\mathrm{Bi}$ below 100 MeV. The analysis is performed in terms of comparing the theoretical results with the available experimental data. A satisfactory agreement is observed in the whole energy and target mass regions. Moreover, the elastic-scattering angular distributions and reaction cross sections of $^{9}\mathrm{Be}$ on some lighter targets are also predicted using the global optical model potential and a reasonable description of the experimental data is obtained.
