Coulomb barrier and up to 200 MeV in the reactions 4, 6 He+ 209 Bi and 7 Li+ 208 Pb were
done. The secondary 4, 6 He beams were produced using the beam-transport line of the
U400M accelerator at FLNR, JINR. The experimental fusion and fission excitation functions
obtained for the different reactions 4, 6 He+ 209 Bi and 7 Li+ 208 Pb and leading to the
same compound nuclei 213, 215 At were analyzed using the PACE-4 and CCFULL.
