Abstract
Relative energies and relative intensities of the K alpha satellites and the K beta bands of Mg and Al metals and anodized Al have been measured. Spectra were obtained with a PAX spectrometer which provided high resolution and accurate intensity data (PAX identical to photoelectron spectrometry for the analysis of X-rays). Relative energies agree well with data from the literature. Relative intensities of line groups that correlate with initial KL, KL2 and KL3 defects are compared with theoretical predictions based on the shake-off theory. Theory underestimates the satellite group intensities by 15% for KL defects and 30-40% for KL2 defects. The intensity ratio K beta /K alpha 1,2 is found to be 1.7% for Mg and 2.4% for Al.
