Abstract: The Li-6 + Si-28 elastic scattering was studied at near-barrier energies with the aim to probe the threshold anomaly. Angular distributions were measured over a wide angular range (theta(lab) = 25degrees to 150degrees) at 4 energies, namely, 7.5, 9, 11 and 13 MeV The present data together with previous ones at higher energies, as well as elastic scattering data of Li-6 on various targets at near barrier energies, were analyzed by using optical potentials obtained in a double-folding framework. It was found that the strength of the real part of the potential remains almost independent of energy down to, and possible even below, barrier, while the strength of the imaginary part presents an increase at near barrier energies. The results are discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
