The relaxation of an electron excited to the high energy region, is
accompanied by the creation of various excitations (plasmons, quasi-particles,
phonons). The stages of this many-body, non-stationary phenomenon (cascade) are
described microscopically. The electron distribution function 
and
characteristic times for the whole energy range, are calculated.
