  Computer simulation studies of aqueous solutions of argon are performed from
ambient to supercritical conditions by using a recent polarizable potential
model (BSV) and the non polarizable simple point charge extended (SPC/E) model.
At T=673 K we compare the water-solute pair correlation functions of the
argon-water mixture with recent experimental results obtained from neutron
scattering experiments. The comparison shows that the introduction of the
polarizable effects decreases the solute-water repulsion and improves the
agreement with the experiment at supercritical conditions. In particular we
find that the water-solute structure predicted by the polarizable model is in
good agreement with the experiment.
