Almandine, pyrope and spessartine garnets were investigated. The samples were irradiated with 10 MeV electron energy to fluencies of 2 × 10 cm for one hour. After irradiation, the Cr ion absorption band decreased but the Fe ion increased in the UV-visible and Fourier transform infrared (FT-IR) spectra of pyrope garnets. In the spessartine samples, the absorption bands of Mn decreased but Fe increased. However, there was no significant change in the almandine garnet spectra. Electron…
