ALUMINUM K-EDGE XAFS OF GIBBSITE AND RELATED-COMPOUNDS

X-ray absorption spectra have been measured in total-electron yield mo de at the aluminum K edge in gibbsite and related compounds. The exper iments were carried out at the UVSOR storage ring in Okazaki, Japan, w hich is particularly suitable for these measurements because of its re latively low intensity which permits the use of a quartz monochromator without causing radiation damage to the quartz. It is shown that XAFS spectra of good quality can be obtained.
