| Abstract: | We have observed high resolution 13C NMR spectra in k-intercalated stages 2, 3, 4 and 6 HOPG compounds. The sample was a block itself or sliced one of HOPG. From T1T of each resolved line we obtained a distribution of density of states N(EF) at the Fermi level among the graphite layers. |
