A theoretical model for the charge equilibration in heavy ion collisions

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

We propose to treat the charge equilibration process as a collective high frequency mode and discuss the implications for the first stages of a heavy ion collision. We show how its dynamics can be treated by means of a quantal master equation. We solve numerically the dynamical equations for a two-dimensional model, using charge excess and mass asymmetry as dynamical degrees of freedom.
