ions, electrons and UV photons can bombard surfaces
on outer solar system bodies causing sputtering and chemical change
in the surface material (radiolysis and photolysis). This can lead to
the production of an ambient gas and can determine the reflectance
properties of these bodies. Here we work closely with a number of
laboratory groups to accumulate a data base and then we apply these
results to observations of bodeis in the outer solar system.
