Show affiliationsPositronium annihilation has been related to the condensation of oxygen on silica and alumina powder. Doppler-broadening measurements on the 511 keV annihilation line, together with 3 gamma /2 gamma determinations, reveal the early stages of molecular adsorption. An application of the Langmuir model yields values of 1130 K and 1630 K for the respective adsorption energies.
