Abstract
A correlation between the photoacoustic (PA) and optical absorption (OA) spectra of X-irradiated NaCl:Y crystals is reported. The F-band spectra observed through PA spectroscopy is found to be sharper than that of OA spectroscopy. This sharpening is attributed to the reduced probability of nonradiative decay processess of F-Centres over the radiative processes. Two bands observed in the UV region of both the spectra are attributed to the Y+ impurity transitions in the host matrix.
