The weakly bound nuclei have been extensively studied during the last decades. Because the halo nuclei have small separation energy and the halo nucleons are located in the orbit with low angular momentum,these nuclei are expected to behave differently from stable nuclei[1]. Elastic scattering is one of the best probes to study nuclei on the dripline,which is therefore a major ingredient in attempts to understand the properties of unstable nuclei The weakly bound nuclei have been extensively studied during the last decades.
