There are two effects associated with the solid surface:a) alteration
of the bulk modes of the infinite solid and b) the appearance of new s
urface - specific modes. Most of our knowledge about solid surface (co
mposition. ordering. atom dynamics, interaction energy of some molecul
es with solids), as well as other properties has been supplied by spec
troscopic method; these methods afford basically the variation of the
characteristics of an incident particle beam (electrons. photons. ions
etc.) as it emerges after the interaction with the solid surface in q
uestion. The incident beam employed in spectroscopy interacts with the
surface modes and only the knowledge about these modes allows one to
transform the variation of beam properties into information regarding
the surface This contribution deals with the solid surface plasma osci
llation, one of the b) type modes,
