It is found that the metallic character of the BaCo1-xNixS2 system increases with x in accordance with the results of transport property measurements. The S L-2,L-3 X-ray emission spectra show an excitation energy dependence which allowed separate mapping of the distribution of S(2) and S(1) S(2) 3s3d partial density of states.
