| heal.abstract | The Li-7 +Si-28 elastic scattering was studied at near-barrier energies., namely, 8, 8.5, 9, 10, 11, 13, 15, and 16 MeV, with the aim to map the real and imaginary part of the optical potential and therefore probe the threshold anomaly. Angular distributions were measured over a wide angular range of (theta(lab)=25degrees to 150degrees) for the lower energies and of (theta(lab) = 10degrees to 100degrees) for the higher energies. The present data, together with previous ones on heavier targets (Ba-138 and Pb-208) at near barrier energies, were analyzed by using optical potentials obtained in a double-folding framework. The results were compared with previous measurements of Li-6 on the same targets. It was found that a striking difference occurs between the imaginary potentials of Li-6 and Li-7, which, respectively, present an increasing and decreasing behavior approaching the barrier from higher to lower energies. On the other hand, this energy variation is not fully reflected to the real part of the potential, as it is described by dispersion relations. The strength of the real potential remains almost constant with a weak declining and uprising trend for the Li-6 and Li-7, respectively. For a better understanding of our results, continuum-discretized-coupled-channel calculations were also performed and are discussed. | en |
