In the present work we study the effect of the breakup channel of the proton halo on the other reaction mechanism for the system involving the projectile 8B and a heavy target 208PB. It is found in the literature that the breakup of neutron-halo projectile damp the elastic scattering angular distributions, especially at angles near the Coulomb – nuclear interference peak. Strong damp was found for the 11Li + 208Pb  system due to E1 excitation of the projectile to the continuum states. Some damp was also observed for other systems for reactions involving the 6He neutron halo projectile [2 - 4], due to Coulomb-nuclear breakup interference. Recently Y.Y. Yang et al.  measured the elastic scattering angular distribution for the 8B + 208Pb system at about three times the Coulomb barrier. They found almost no influence of the breakup channel on the elastic scattering at this high energy. Recent work  shows that the breakup of the 8B projectile almost does not affect the elastic scattering angular distribution of its interaction with 58Ni. In the present work we show that in the case of the interaction of 8B with heavy target, a damp of the elastic scattering is observed too, mainly dominated by the Coulomb breakup, with a very weak influence of the nuclear breakup. It is observed a contribution of the dipole and quadrupole interactions of the same orders. A strong dependence on the binding energy of 8B is observed in our conclusions. A detail study of the reaction mechanism is performed for the 8B + 208Pb system at near barrier energies.
