| Abstract: | Elastic scattering of ~(10)Be on a ~(208)Pb target was measured at E_(Lab)=127 MeV,which corresponds to three times the Coulomb barrier.The secondary ~(10)Be 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 ~(10(Be+~(208)Pb 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. |
