  The electronic structure of the natural topological semimetal
Co$_3$Sn$_2$S$_2$ crystals was studied using near-edge x-ray absorption
spectroscopy (NEXAFS) and resonant photoelectron spectroscopy (ResPES).
Although, the significant increase of the Co\,$3d$ valence band emission is
observed at the Co\,$2p$ absorption edge in the ResPES experiments, the
spectral weight at these photon energies is dominated by the normal Auger
contribution. This observation indicates the delocalised character of
photoexcited Co\,$3d$ electrons and is supported by the first-principle
calculations. Our results on the investigations of the element- and
orbital-specific electronic states near the Fermi level of Co$_3$Sn$_2$S$_2$
are of importance for the comprehensive description of the electronic structure
of this materials, which is significant for future applications of this
material in different areas of science and technology, including catalysis and
water splitting applications.
