Abstract

Angular distributions of transfer reaction 208Pb(7Li, 6He) 209Bi were measured at Elab(7Li)= 21.2, 24.3, 25.67 and 28.55MeV. By fitting the experimental data with the theoretical frameworks of Distorted Wave Born Approximation (DWBA), the optical model parameters of the halo nuclear system 6He+209Bi were extracted. The breakup threshold anomaly (BTA) was observed clearly in the imaginary potential, and a further decreasing trend in the deep sub-barrier region was observed for the first time in a halo system. Furthermore, the dispersion relation is found of no use to describe the connection between the real and imaginary parts.
