摘要The peripheral heavy-ion collisions of Sn-112,Sn-124+Kr-86 at E-b=25 A MeV are studied by means of the improved quantum molecular dynamics model (ImQMD). It is shown that the slope of the average N/Z ratio of emitted nucleons versus impact parameters for these reactions is very sensitive to the density dependence of the symmetry energy. Our study also shows that the yields of H-3 and He-3 decrease with impact parameters and that the slope of the yield of H-3 versus impact parameters as well as the ratio of Y(H-3)/Y(He-3) depends strongly on the symmetry potential for peripheral heavy-ion collisions.
