N2 - Photoemission spectra of single crystal CeSix (x=1.86; nonmagnetic, TK∼20 K, and x=1.7; ferromagnetic, Tc=13.7 K) were measured at very high-energy resolution and low temperature. The Fermi-edge band in the photoemission spectrum of CeSi1.86 is narrower and closer to EF compared with the previous reports on polycrystals, showing closer resemblance to the calculation based on the Kondo model. The intensity of the Fermi-level peak is drastically reduced in going from CeSi1.86 to CeSi1.7, which is in good qualitative agreement with the Kondo model.
