Scientific paper

Low energy electron induced radiolysis of ices and surrogates of outer solar system bodies such as icy moons and comets have been investigated. Low energy electrons are effective simulants of high energy charged particle irradiation. Molecular hydrogen emission from comets is used to gain information about the formation temperature and isotopic branching in these primordial solar system objects. Long term storage of comets in the Kuiper belt and Oort cloud can subject these objects to space weathering due to galactic cosmic rays and other radiation. Stimulated desorption of atomic and molecular hydrogen and oxygen occur from these ices as well as water group ions. Yields and internal energy distributions of H2 and D2 from laboratory ices have been measured. Ortho-para hydrogen spin isomers have been observed and their equilibration temperatures determined. These spin isomers carry information about the formation temperature of the ice as well as the mechanisms of space weathering that can influence interpretation of the origin and evolution of ice covered bodies.
