Abstract
High-resolution - and y-projected fine structure for the 1s carbon core level in graphite are compared with symmetry-projected calculations. A very sharp transition occurs about 7.6 eV above the Fermi energy in the y results, agreeing closely with the nondispersive band. An additional feature near 8.5 eV above the Fermi energy may be due to the branch of the free-electron-like interlayer states. With a modest excitonic distortion, the results agree closely with the expected band.
