Abstract
The Boltzmann–Uehling–Uhlenbeck (BUU) approach with density fluctuations was used to study the density dependence of the asymmetry term in the nuclear equation of state (EOS). The isospin diffusion and equilibration process was investigated. The isotopic ratios of light particles were not sensitive enough to distinguish between asy-stiff and asy-soft EOS. However, the isospin ratio seems to be more sensitive to the density dependence of the asymmetry term in the nuclear equation of state and it favors a more asy-stiff equation of state.
