The Ni and Co monosilicides and disilicides are studied by soft-x-ray-emission spectroscopy. The Si {ital L}{sub 2,3} spectra, which provide a measure of the partial densities of states of {ital s} and {ital d} angular momentum symmetry (({ital s}+{ital d}) PDOS) localized on the Si site, are compared with available theoretical calculations, and discussed in terms of the contribution of {ital s} electrons to the bonding. The Ni and Co {ital M}{sub 2,3} emission spectra are also obtained, and analyzed to provide information about the {ital d} PDOS localized at the metal site. These spectra are discussed in terms of {ital p}-{ital d} bonding in the silicides.
