Inertia effects in the mass transport of heavy ion reactions

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

Mass transport is described as a damped motion including inertia and a Gaussian stochastic force. The inertia coefficient is estimated in a hydrodynamical model, the damping coefficient by volume dissipation as well as by wall dissipation. Depending on the strength of the restoring force the mass-transfer degree of freedom may show inertia effects. In particular, underdamped motion cannot be excluded. The time development of the mean value 〈A〉 t and the varianceΓ t is given in the overdamped as well as in the underdamped regime. The main effect of the inertia is a slower initial increase ofΓ t . A small-amplitude oscillatory behavior ofΓ t is possible in a moderately underdamped situation.
