摘要
用电子自旋共振方法研究光纤的γ射线辐照缺陷情况。结果发现，射线辐照产生一系列同磁缺陷，缺陷中心的浓度随着辐照剂量的增加而增加；缺陷的种类主要是Ｅ＇心、非桥连氧空穴心和过氧根（ＯＨＣ）心，并对它们形成的机制进行了分析和讨论。
Abstract The γ-ray radiolytic defect in optical fiber has been studied by the electronspin resonance method. It is found that a series of paramagnetic defects have been formed by the γ-ray irradiation;the densities of the defect centers increase withthe irradiation doses, and the types of defects are mainly the E' center, the non-bridging oxygen hole center and the perody radicai (OHC). The defects productionmechanism is also discussed.
