Semiclassical phase space approach for the charge equilibration fluctuations in heavy ion reactions

The fluctuations of the isobaric distributions in deep inelastic collisions are related to the in-phase excitation of the isovector giant dipole resonances of each nucleus. The characteristics of the zero point motion are obtained by the phase space approach method. The calculations are performed for various systems as a function of the interdistance between the collision partners. Estimations are given for density overlap corresponding to the top of the fusion barrier. (orig.)
