Abstract: It is shown that recently revealed unusual energy dependence of the optical potential, describing the elastic scattering of ⁹Be by ²⁰⁹Bi at near barrier energies, is removed when Coulomb polarization potential is introduced in the optical potential. Such optical potential has "normal" energy dependence and satisfy dispersion relation at strong absorption radius. Сalculation of "fusion" (complete + incomplete fusion) and total peripheral reaction cross sections also indicate necessity of inclusion of Coulomb polarization potential in the optical potential when analyzing elastic scattering differential cross sections for ⁹Be + ²⁰⁹Bi system at near barrier energies.
