  Calculations predict a connection between the isotopic composition of
particles emitted during an energetic nucleus-nucleus collision and the density
dependence of the asymmetry term of the nuclear equation of state (EOS). This
connection is investigated for central 112Sn+112Sn and 124Sn+124Sn collisions
at E/A=50 MeV in the limit of an equilibrated freezeout condition. Comparisons
between measured isotopic yields ratios and theoretical predictions in the
equilibrium limit are used to assess the sensitivity to the density dependence
of the asymmetry term of the EOS. This analysis suggests that such comparisons
may provide an opportunity to constrain the asymmetry term of the EOS.
