Abstract

The energy dependence of total cross sections of reactions⁶He + Si and^6,9Li + Si in the beam energy range 5-30 MeV/nucleon has been measured. An agreement with the published experimental data for the reaction 6 He + Si was obtained. For the reaction⁹Li + Si new data in the vicinity a local enhancement of the total cross section was obtained. Theoretical analysis of possible reasons of appearance of this peculiarity in the collisions of nuclei⁶He and⁹Li with Si nuclei has been carried out including the influence of external neutrons of weakly bound projectile nuclei.
