Isospin fractionation and isoscaling in dynamical simulations of nuclear collisions

Isospin fractionation and isoscaling are found to hold for isotopes from nuclear collisions simulated within the anitsymmetrized molecular dynamics model. The observed linear relation between the isoscaling parameter and the fragment isospin asymmetry [Formula Presented] of the liquid corroborates, in particular, the applicability of statistical considerations to the dynamical fragment emission. Using the derived relation, we are able to extract statistical parameters from the outcome of the dynamic evolution of collisions. The relation allows to access the symmetry energy in the equation of state. This is consistent with the previous findings that the isoscaling parameters can be used to limit the symmetry energy parameter in the nuclear equation of state.
