The SCF-X..cap alpha.. scattered-wave method has been used in the quasirelativistic approximation to calculate the energies and relative intensities of the transitions in the M/sub 4/, /sub 5/N/sub 4/,/sub 5/V and N/sub 4/,/sub 5/VV Auger electron spectra AES of lanthanum in the LaO/sup 9 -//sub 6/ cluster, which is taken as a model for crystalline La/sub 2/O/sub 3/. A study has been made of the influence of relaxation effects on the AES. The AES intensity distribution is largely determined by the population of the 4f states of La in the initial state of the Auger process. The AES for lanthanum in La/sub 2/O/sub 3/ are interpreted from the calculations.
