We report the results of the study by angle-resolved photoelectron spectroscopy of intercalated compound Cr1/3TiTe2 . In the range of binding energies up to 6eV we obtained band mapping along Gamma-M , Gamma-M' , and M-K directions of the Brillouin zone. It was established that electronic structure of TiTe2 changes substantially under the inclusion of Cr. An additional, essentially dispersionless band appears at ˜1eV below the Fermi level. Band structure calculations allow one to interpret this band as being due to the Cr3d-Ti3d mixed states. An almost dispersionless character of this band allows one to presume a polaronlike nature of Cr-Ti mixed states.
