Resonant photoemission of CoCl2

We present the results of a study of the resonant photoemission from polycr ystalline in situ evaporated thin him of CoCl2 excited at 2p photoabsorptio n edges of Co and Cl. At the Co 2p-->3d resonance strong enhancement was ob served for the Co 3p, valence band photoemission and for spectral regions o f L23M23M23, L23M23M45 and L23M45M45 Auger transitions. The results of vale nce band resonant photoemission is discussed in terms of the available calc ulations. The valence band resonant spectra exhibit no enhancement in conne ction to the Cl 2p edge which shows that the Cl 2p absorption pre-edge stru cture is formed by d- and s-like final delocalized states.
