Abstract
The experimental angular distributions for [Formula: see text]-particles elastically scattered from [Formula: see text]C nucleus in the energy range 48.7–386[Formula: see text]MeV and for 6He+[Formula: see text]C nuclear system in the energy range 5.9–493.8[Formula: see text]MeV have been reanalyzed. Data analysis is performed within the framework of both optical model (OM) and double folding optical model (DFOM). In this model, the real part of the potential is generated using the double folding procedures based on the effective M3Y interaction between projectile nucleons and target nucleons in addition to an imaginary part of Woods–Saxon (WS) form. Two criteria are used in order to observe the nature of 4He and 6He elastically scattered from [Formula: see text]C and the effect of the two neutron halo structure of 6He. First, the extracted potential parameters are utilized for calculating the reflexion coefficients [Formula: see text] which is strongly related to angular momentum [Formula: see text]. Second, the reduction in reaction cross-sections with the projectile’s energy.
