The N04sub(,)5N6sub(,)7 and N4sub(,)5N6sub(,)7O4sub(,)5 Auger spectra of Au, Pt and Ir

The relative intensities of N4sub(,)5N6sub(,)7sub(,) N4sub(,)5N6sub(,)7O4sub(,)5 and N4sub(,)5 N6sub(,)7O2sub(,)3 transitions in clean Au, Pt and Ir are measured, and the relative roles of super-Coster-Kronig and Coster-Kronig de-excitation of N4sub(,)5 holes are discussed. Super-Coster-Kronig transitions account for more than half the de-excitation in Au, and become increasingly dominant as the number of O4sub(,)5 electrons in the metal decreases. (orig.)
