摘要：

An electron spin resonance investigation of a series of low-silica-content (less-than-or-equal-to 20 mol%) calcium aluminosilicate glasses has been performed. The compositional dependence of the X-ray-induced defects is found to be consistent with the proposed dependence of the number of non-bridging oxygens on the CaO/Al2O3 ratio and the silica content. Computer lineshape simulations of the experimental data have led to the identification of two variations of aluminum-oxygen hole centers.
