Abstract
The K emission band of graphite was observed using a grazing incidence spectrometer, and unfolded with the use of Gaussian window function. The unfolding procedure reveals the intrinsic profile of the state density. The profile consists of four sub-bands. The highest one is π-band and the lower three are σ-bands. The overlapping between them is very small. The height of the Fermi edge is about one fortieth of the peak of the π-band. The width of the π-band is 5.8 5 eV. The ratio of the effective number of electrons per atom for π-and σ-electrons is estimated to be 0.9:3, which suggests a slight mixing between them. It is also estimated that the three σ-electrons are distributed equally into the three parts of the σ-band. The low energy tail is classified as a satellite.
