We have made the XAFS measurements at the Cr-K-edge on natural Indian ruby single crystals (corundum) and its two irradiated samples with fluence 1 × 1012Ni6+ and 5 × 1012Ni 6+ions/cm2. Irradiated samples show interesting changes in their physical appearance. XANES measurements show progressive decrease in Δoct value on increase of Ni fluence in irradiated samples. EXAFS measurements on these samples show decrease in Cr-O distance on increase of Ni fluence. Lowering of Δoct value is correlated with the increase of Cr-O distance. © 2004 Elsevier B.V.
