XENON SPECTATOR AND DIAGRAM L-3-M4,5M4,5 AUGER INTENSITIES NEAR THE L-3 THRESHOLD

Calculations based on the theory of radiationless resonant Raman scatt ering are employed in the interpretation of new Xe L-3-M4,5M4,5 Auger spectra recorded using synchrotron radiation tuned to energies across the L-3 edge. Fits of theoretical line shapes to the spectra are emplo yed in separating intensities due to nd spectator (resonant) and diagr am Auger processes. Near-threshold Anger intensity, previously attribu ted to diagram decay, is found to be due to the large-n spectator line s that result from postcollision-interaction-induced ''recapture'' of threshold photoelectrons to nd orbitals.
