摘要：

The elastic scattering of Li-6 and Li-7 by Pb-208 has been measured at several energies near the Coulomb barrier and analysed in terms of the optical model. Previous reports have suggested that the normalization factor, N(R), for the double-folded real potential is approximately 0.6 for both isotopes at bombarding energies well above the Coulomb barrier. In this paper we show that, whereas this low value for N(R) persists for Li-6 at energies close to the barrier, for Li-7 it is somewhat greater than unity, and indicates the existence of a threshold anomaly for this projectile.
