摘要：

The 74 and 13 G electron paramagnetic resonance hydrogen hyperfine doublets of the Si E' center were observed in low-OH content, oxygen-deficient silica optical fibers exposed to hydrogen at room temperature. These spectra were also found in hydrogen treated bulk samples but at negligible intensities compared to those in fiber samples. The significant enhancement of these doublets in the fiber samples indicates that the precursors of the 74 and 13 G hydrogen hyperfine doublets of Si E' are substantially produced in the fiber drawing process. Possible structures of the two precursors are discussed.
