Dynamical aspects of isoscaling

Nuclear Theory 2009-11-11 v1

Abstract

The origin and dynamical evolution of isoscaling was studied using classical molecular dynamics simulations of 40{}^{40}Ca + 40{}^{40}Ca, 48{}^{48}Ca + 48{}^{48}Ca, and 52{}^{52}Ca + 52{}^{52}Ca, at beam energies ranging from 20 MeV/A20 \ MeV/A to 85MeV/A85 MeV/A. The analysis included a study of the time evolution of this effect. Isoscaling was observed to exist in these reactions from the very early primary isotope distributions (produced by highly {\it non-equilibrated} systems) all the way to asymptotic times. This indicates that isoscaling is independent of quantum effects and thermodynamical equilibrium. In summary, collision-produced isoscaling appears to be due more to the mere partitioning of the proton-neutron content of the participant nuclei, than to specific details of the reaction dynamics.
