| Popis: | In order to study the influence of the breakup channel in the elastic scattering of the 6,7Li+80Se systems, we have measured angular distributions at center- of-mass energies from 13 ≤ Ec.m. ≤ 24 MeV (0.8VCB up to 1.6VCB ). They were analyzed within the framework of the optical model to study the energy dependence of the real and imaginary parts of the nuclear potential. The focus was to investigate the threshold anomaly in those weakly bound systems. The behavior of the calculated potentials as a function of energy indicates that our results are consistent with the dispersion relation. The threshold anomaly was observed in the 7Li+80Se system and the breakup threshold anomaly was confirmed for the 6Li+80Se system. |
