For ions  grazingly  impinging  on  a  SnTe surface, the electron
emission due to  binary  collisions with the free-electron gas is
investigated  by  employing  a    semiclassical  formalism.    We
calculate the contribution of this  process to the energy spectra
of  the  ejected  electrons, and compare  our  results  with  the
available experimental data.
