520 _aThe analyses of the optical absorption spectra confirm the results obtained from the electrical studies Analyses of the IR spectra for the samples yields some band intensity changes and position shifts of some important spectral bands which indicate the structural modifications induced by fast neutron irradiation In addition , the transmittance values and the induced changes in the color parameters may indicate that the variation induced coloration is both concentration and radiation dependent
