We have performed precision elastic backscattering measurements for the weakly bound nuclei 6,7Li on the medium and heavy mass targets 58Ni, 116,120Sn and 208Pb at sub- and near-barrier energies (Ec.m./Vbar = 0.6 to 1.3). Excitation functions of elastic scattering cross-sections have been measured at ±160◦ and ±170◦ and the corresponding ratios to Rutherford scattering and relevant barrier distributions have been extracted. These measurements complement recent work on a 28Si target, for probing systematically the potential at sub- and near-barrier energies and relevant reaction mechanisms, while indicate a possible breakdown of the dispersion relation.

Abstract

We have performed precision elastic backscattering measurements for the weakly bound nuclei 6,7Li on the medium and heavy mass targets 58Ni, 116,120Sn and 208Pb at sub- and near-barrier energies (Ec.m./Vbar = 0.6 to 1.3). Excitation functions of elastic scattering cross-sections have been measured at ±160◦ and ±170◦ and the corresponding ratios to Rutherford scattering and relevant barrier distributions have been extracted. These measurements complement recent work on a 28Si target, for probing systematically the potential at sub- and near-barrier energies and relevant reaction mechanisms, while indicate a possible breakdown of the dispersion relation.
