摘要：

The particular structure of KLL Auger emission of oxygen in cadmium oxide was investigated. The strong doublet detected at 510 and 515 eV, interpreted in terms of inter-atomic transition KVV adjacent to the intra-atomic line KL23L23, corresponds to an intrinsic behaviour of cadmium oxide under electron excitation. The high intensity of the inter-atomic component at 515 eV results from relaxation and screening effects connected to the presence of Cd-4d holes. This Auger structure is magnified in CdO because of the high cross-section for cadmium Auger emission combined to a relative long lifetime of the Cd-4d holes produced by the Auger cascade through the electron structure of CdO. This typical spectrum was observed from bulk CdO oxide as well as from the oxidized surface of metallic cadmium. Among the series of 4d metals, cadmium also displays a special oxygen affinity in the presence of electron irradiation.
