摘要：

The pi-electronic excitations in graphite layers are studied within the self-consistent-field approach. The pi plasmon behaves as an optical plasmon, mainly due to the pi-band characteristics. The excitation spectra and the pi-plasmon frequencies are obviously enhanced by the interlayer Coulomb interactions and increase with the number of graphite layers.
