5. Plasmons which are created by collective excitations of the valence band• Extrinsic Plasmon: excited as the energetic PE propagatesthrough the solid after the photoelectric process.• Intrinsic Plasmon: screening response of the solid to the suddencreation of the core hole in one of its atomThe two kinds of Plasmon are indistinguishable.6.
