Description

The determination of trace levels of oxygen in germanium by activation analysis with 45-MeV α-particles is described. The chemical separation of 18F formed from oxygen consists of repeated distillation of fluorosilicic acid followed by precipitation of lead chlorofluoride and allows a reduction of the matrix radiation by a factor of 4.106. Oxygen concentrations of about 20 ng g-1 are found for high-purity germanium; for oxygen doped monocrystals, oxygen concentrations of 400 and 700 ng g-1 are found. The influence of surface contamination on the final results is studied
