Abstract

Oxygen diffusion in crystalline SiO (natural quartz) has been measured by an activation analysis using the reaction O18 (p,n) F18. Before the activation, the single-crystalline samples with a well-polished surface were annealed in 18O-enriched oxygen gas. The annealed samples were irradiated perpendicular to the polished surface with 2,7 MeV-protns. Part of the O18 in the sample is transformed to F18 which is a β+-radiator with a half-life of 110 minutes. The 511 keV annihilation radiation is used as a measure of the 18O-content in the sample.
