Auger electron-ion coincidence spectrometry after electronic excitation of L-shell in argon

摘要

We report the results of coincidence measurements of Auger electron-ion pairs generated by 1 keV electron beam bombardment of argon where,for the first time,the electron energy resolution is comparable to the natural width of 2p hole.The L-MM Auger spectrum is decomposed into contributions related to the specific final ionic charge states Ar~(2+)to Ar~(5+)allowing the study of decay schemes which lead to different structures in the non-coincidence Auger spectra.
