Abstract
Experimental angular distributions for the weakly bound Be-9,Be-10 nuclei elastically scattered from Pb-208 target at various energies are investigated using phenomenological and microscopic potentials. The considered data in this study are: Be-9+Pb-208 in the energy range of 37.0 - 75.0 MeV and Be-10+Pb-208 in the energy range of 38.4 - 43.9 MeV. The performed analysis reflects the nature and peculiarities of the considered projectiles. For the Be-9+Pb-208 nuclear system, the data showed a typical Fresnel diffraction scattering pattern and the Coulomb rainbow phenomenon is well presented due to the interference between partial waves refracted by the Coulomb and nuclear potentials. The Li-7+d and Be-9+n cluster structures of Be-9 and Be-10, respectively are studied. The extracted renormalization factors for the real part of potential constructed on the basis of double folding as well as cluster folding could reflect the nature of the loosely bound projectiles.
