The spin-polarized sulfur /ital L//sub 2,3/VV Auger spectrum isrecorded for the system /ital c/(2/times/2)S/Fe(001). Convolution of thecalculated spin-dependent projected local density of states gives goodagreement with the measured spectrum. As in previous studies a strong satelliteis observed in the Auger spectrum and this is shown to be due to the presenceof hybridized iron states at the sulfur site. The spectrum also shows anexchange splitting of 0.2 eV in reasonable agreement with the calculation. Theintegrated spin-up and spin-down Auger intensity gives an estimate of themagnetic moment of the sulfur adsorbate less than or equal to0.10..mu../sub /ital B//.
