Experimental study of the elastic scattering of 10 Be on 208 Pb at the energy of around three times the Coulomb barrier

Elastic scattering of Be-10 on a Pb-208 target was measured at = 127 MeV, which corresponds to three times the Coulomb barrier. The secondary Be-10 beam was produced at the Radioactive Ion Beam Line in Lanzhou of the Heavy-Ion Research Facility in Lanzhou. The angular distribution of elastic scattering in the Be-10 + Pb-208 system shows a typical Fresnel diffraction peak. Optical model analysis of the angular distribution was performed using the Woods-Saxon, double-folding and global potentials. With the global potential, different density distributions were used. The results indicate that different density distributions for the projectile induce distinct effects in the angular distribution.
