    "abstract": "An analysis of the real and imaginary part of the polarization potential in\nterms of the relative contributions of the single collective states for the $\n^{208}Pb + ^{208}Pb $ system has been done. The polarization potential has been\ncalculated within the Feshbach formalism taking into account the collective\nstates calculated with the Wigner function moments method. The contribution of\nthe isoscalar giant dipole resonance states has been estimated being of the\norder of 10 - 20 \\% of the total at relatively low incident energy.",
