Excitation functions of the reaction products were measured for the reactions induced by He-4,He-6 projectiles on Pb-206,Pb-208 targets, leading to the same compound nucleus. This was accomplished by using the stacked-foil-activation technique. The identification of the reaction products (accumulated in the Pb targets) was done by their radioactive alp ha decays. The excitation functions for the 2n evaporation channels were obtained at energies below the sub-Coulomb barrier region. A large value of the fusion cross section was observed in the case of the reaction induced by the weakly bound He-6 projectile.
