The study of the temperature dependence of the 12.0-mT hydrogen EPR hyperfine doublet in wet and dry silica, between 120 and 300 K, has shown a reversible variation of the number of defects, inversely proportional to an intensity change of the signal attributed to the holes trapped at substitutional aluminum sites. This correlation suggests a model of the point defect responsible for the 12.0-mT EPR signal: The H atom is close to an Al atom and two different alternative electronic configurations are possible, depending on the temperature. © 1989 The American Physical Society.
