The change of their transmissivity is studied over 320~1000 mĪ¼ wave length range. Fading phenomena, time variation and temperature dependence are studied. The time dependence of the fading is expressed by the formula which is proportional to t-šœ† approximately (šœ† is constant). From the excitation curve, four or more centers can be assigned. Refering to the ESR-measurements and other works, the structure of these centers are determined and the production mechanism is discussed. These interpretation can explaine the experimental results well.}, pages = {237--264}, title = {On the optical properties of irradiated cobalt glass and other glasses}, volume = {28}, year = {1977} }
