A local L-independent polarization potential due to dipole Coulomb excitation is derived with the use of the semiclassical Coulomb excitation amplitudes. It is showed that an analytic form for the imaginary polarization potential can be obtained for arbitrary dipole excitation energy while the real polarization potential is related to the imaginary part through a dispersion relation. The relative importance of the real and imaginary parts of the polarization potential is illustrated for the case of the collision of 11Li and 208Pb at different projectile energies.
