Abstract
The lifetimes of o-positronium in silica gel adsorbed with various amounts of water, n-hexane, or nitromethane were measured. The fraction of o-positronium escaping the condensed phase can be related to the specific area and the pore volume of the silica gel. The mean life of o-positronium in the pores is found to be very sensitive to the surface properties of silica gel. The formation of free radicals on the surface of silica and the reactions between these free radicals and o-positronium are suggested as the explanations.
