Decay of the , and states of Ar studied by utilizing the Auger resonant Raman effect

Abstract
The 2p electrons of Ar have been excited selectively to the 4s, 3d and 4d orbitals and high-resolution de-excitation spectra have been recorded by utilizing the Auger resonant Raman effect. Fine structures in the resonant Auger spectra have been clearly resolved for the first time. The roles of shake transitions and configuration interaction between the and , n = 3 - 6 final states in producing the complicated fine structures have been discussed.
