Abstract

Auger decay process following multielectron excitation accompanying F 1s photoionization of CF4 molecule has been studied in the excitation energy range between 700 and 750 eV using angle-resolved Auger electron spectroscopy. The observed spectra have shown an enhancement in the specific band, at an electron kinetic energy of ∼ 644 eV, only in the spectrum recorded at 710 eV excitation energy of horizontally polarized light. This feature is discussed in terms of the resonant Auger emission originated from the doubly excited state. The evolution of spectral shape has also exhibited the excitation energy dependence above the threshold of multiple excitation. The origin of the spectral variation is considered due to gradual growth of the satellite Auger lines originated from the multielectron excitation.
