Abstract: | Auger spectra have been recorded from elements of the first transition series using a hemispherical analyser. Highly resolved LMM spectra were obtained showing for the first time the composite nature of these peaks for many of the elements studied. The recorded spectra show a general similarity for the elements Sc → Zn but interesting differences emerge. At the beginning of the transition period the L3 based transitions have the relative intensities L3 M2,3, M2,3 > L3 M2,3, M4,5<> L3 M4,5, M4,5 whereas towards the end of the series the order L3 M4,5, M4,5 > L3 M2,3, M4,5<> L3 M2,3, M2,3 is observed. Pronounced chemical shifts have been observed upon oxidation. The spectra are interpreted in terms of an L -S coupling scheme and the fine structure discussed in terms of effects produced by multiplet splitting. |
