Radiation of relativistic particles in single crystals

Channeling and radiation of 855 MeV electrons and positrons in straight and bent tungsten (1 1 0) crystals

“…The excess over dE am is due to the emission of the coherent BrS by over-barrier particles which move along quasi-periodic trajectories, traversing the crystallographic planes under the angle greater than Lindhard's critical angle (see Refs. [9][10][11][68][69][70][71] for the reviews on the coherent BrS). The only exception from this scenario are the spectral dependencies calculated for the smaller aperture in the straight (C = 0) and nearly straight (C = 0.01) crystals.…”

Structured targets and the Landau-Pomeranchuk-Migdal effect

“…There have been many papers which extended the classical treatment of the LPM effect including [7], [8], and [9] in which certain errors in the original derivation are corrected. A general and clear treatment of semiclassical photon radiation can be found in the review paper by A.I.…”

Interaction of Channeled Electrons with Lattice Excitations

“…Indeed, using plane waves instead of the states 12) (see, e.g. Section 2.5) and replacing summation over 91 by integration,The above expression coincides with (4.5) of[28] in which the radiation recoil is neglected and the spectral range is restricted by the condition 6 < 911 or 6 x gll.…”
