Abstract
The L1 and L3 x-ray absorption fine structures from the same element in the same material were compared to illustrate the ‘‘join’’ between the x-ray absorption near edge structure (XANES) and the extended x-ray absorption fine structure (EXAFS). In the XANES region the two spectra differed because of the different selection rules; however, the EXAFS spectra were very similar when adjusted for the phase shift. For the oxide samples investigated the L1,3 spectra were similar for E>20 eV which identifies the demarcation between XANES and EXAFS.
