Radiationless Resonant Raman Scattering at the Ar K Edge



Thomas W. LeBrun, S H. Southworth, G B. Armen, M A. MacDonald, Y Azuma


Partial cross sections for Ar K-LZL3(1 D2)np, n=4 and 5 spectator Auger states excited by x-ray absorption across the K-edge were measured and compared with calculations based on the theory or radiationless resonant Raman scattering. Core relaxation and coherence among bound and continuum intermediate states produce shake-up, shake-down, and photoelectron-recapture effects in the cross sections. The width and position of the 4p spectator Auger peak are shown to be sensitive to resonance structure in the partial cross section via averaging over the x-ray bandwidth.
