Global optical model potential for the weakly bound projectile Be9

The global optical model potential for the Be-9 projectile is developed by systematically studying the experimental data of elastic-scattering angular distributions and reaction cross sections from Mg-24 to Bi-209 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 elasticscattering angular distributions and reaction cross sections of( 9)Be on some lighter targets are also predicted using the global optical model potential and a reasonable description of the experimental data is obtained.
