Abstract
Study of fission reactions induced by weakly bound nuclei 6He and 7Li beams on 209Bi and 208Pb targets, leading to the same production of 215At compound nuclei, were investigated. The fission excitation functions for the reactions 7Li + 208Pb and 7Li + 209Bi were investigated to show the effect of targets on the fission cross sections. It was shown that the fission excitation functions for the reactions 6He + 209Bi and 7Li + 208Pb had similar behavior within the experimental error for a broad range of energy. More likely, halo structure of 6He is not reflected on the fission reaction mechanism. Otherwise, a large value of the fusion cross section was observed so far, as it could be expected in the case of weakly bound character of 6He projectile.
