Alumina Alpha Formula: Al2O3 (alpha) Core Loss

Submitted by PD Dr. Peter A. van Aken, April 20, 2005.

Author Comments: - Background subtracted. - Note the absence of the peak at 92 eV (non-dipole transitions due to channeling conditions observed only along <0001>, cf paper quoted).- Calibration could not be accurate. Analyst: Stefan Nufer. Temperature: Room. BEAM/Crystal: <1-100>.
