Aluminium Oxide Alpha Formula: Al2O3 (alpha) Core Loss

Submitted by PD Dr. Peter A. van Aken, November 28, 2007.

Source / Purity: Single crystal

Author Comments: - An arbitrary background was subtracted, because no one know the exact background behind a ionisation edge. Therefore, I do not want to say the absolute intensities are right, but due to the low frequency of EXELFS oscilations.- Calibration could not be accurate Analyst: Stefan Nufer.
