Anomalous energy dependence of optical potential for 9Be + 209Bi system at near barrier energy

It is shown that early identified energy dependence of the optical potential, describing the 9Be elastic scattering on the 209Bi by the near-the-barrier energy, is removed by introducing the coulomb polarization potential into the optical potential. The optical potential obtained with an account of the coulomb polarization potential is characterized by the normal energy dependence and it meets the dispersion ratio on the high absorption radius. The accomplished calculations of the fusion cross sections (fusion and incomplete fusion) and the complete cross sections of the peripheral reactions (the break-down and transfer reactions) also indicate the necessity of accounting for the coulomb polarization potential in the optical potential by the analysis of the optical potential cross sections of the 9Be elastic scattering on the 209Bi at the near-the-barrier energy
