Description
The channeling particles is characterized by the bound quantum states of its transversal motion. Photon interactions with the channeling particles in a single crystal may be accompanied by the energy transitions between the transverse motion levels of channeling particles. The photon combination (Raman) scattering by the quasi-bound channeling particles leads to the appearance of a frequency combination of the incident photon frequency ω_0 and the frequency Δ ω_if , i.e.
ω = ω_0±Δ ω_if ,
where Δ ω_if= 〖ΔE〗_ifγ; 〖ΔE〗_if is the transition energy between “i” and “f” transversal motion quantum states; γ = E/(mc^2 ) is the channeling particles Lorentz – factor. A “violet” satellite (“anti-Stokes” lines ω) analysis in the Raman combination scattering spectrum is suggested. Resonance conditions for observation of the second harmonics (ω = 2ω_0) is discussed.
