  The processes of generation of phonons and electron excitations with quantum
oriented particle in crystal are considered. Expressions are obtained for the
probability of emission of phonons and plasmons with channeled particle. The
theory of the processes of the crystal excitation with the channeled particle,
accompanied by the simultaneous emission of a photon is developed. It is proved
that all the specific features of the electron and phonon crystal excitation
structure appear as components of radiation of the oriented fast charged
particle. The photon emission of a quantum channeled particle, accompanied by a
plasmon excitation in a crystal target is considered. It is taken into account
that the plasmon energy in the crystal is of the same order with the depth of
the potential well in which the channeled particle moves. A weak dispersion of
the plasmons in the crystal is taken into account, which leads to the selection
of the fixed plasmon energy. It is shown that fast charged particle in the rest
frame emits photons with an energy equal to the energy difference between two
quantized levels of transverse motion with the deduction of the net plasmon
energy. The characteristics of photon-plasmon radiation are investigated.
