Résumé :

The geometric scattering theory and the Wentzel-Kramers-Brillouin (WKB) approximation are used to derive explicit expressions for the dynamic polarization potential induced by Coulomb excitation in heavy-ion collisions involving strongly deformed targets. We build two phase-equivalent potentials with very different radial and angular-momentum behaviors, which are discussed in the context of polarization potentials obtained previously within different frameworks. This correspondence provides a recipe for approximately correcting the deficiencies of the geometric scattering approach, which tends to overemphasize the effects of Coulomb coupling. © 1991 The American Physical Society.
