“…Specifically, separating χ-dependent and 2 It should be mentioned that Fig. 1 in [16], corresponding to the total deflection angle 10γ −1 , did not belong to the ultranondipole regime yet, whereas our figure with |χ 1 + χ 2 | ∼ 50γ −1 does. That is responsible for residual differences between the plots.…”

“…At ωT χ 2 /2 → 0, the rings expand to infinity, and the angular distribution of radiation at finite θ [the inner part of Fig. 2(a)] tends to that at single electron scattering through angle χ 1 + χ 2 (cf., e.g., [16]). 2 At some finite ω, the radius of the rings starts to come close to one of the deflection angles.…”

Existence of different types of interference in the spectrum of radiation emitted by a doubly hard scattered electron is demonstrated. The spectrum develops oscillations in two regions: the hard, where the oscillations depend on the electron Lorentz factor, and the soft, where the oscillations depend on the electron scattering angles. This interference pattern owes to the presence of jetlike radiation configurations, formed by a piecewise-rectilinearly moving electron and the accompanying photon. The corresponding nondipole decomposition relation is derived. Notions describing proper field formation and interference, and presumably being applicable more generally, are discussed in detail.

“…The multiple scattering effect on the spectral-angular distribution of the radiation by relativistic electrons in a thin amorphous target was studied in [7]. It was shown that even after the averaging procedure the minimum in the angular distribution of the emitted gamma-quanta is still observed in the initial direction of the electron beam (see Fig.…”

The results of theoretical investigation of angular distributions of radiation from a relativistic electron passing through a thin crystal at a small angle to the crystal axis are presented. The electron trajectories in crystal were simulated using the binary collision model which takes into account both coherent and incoherent effects at scattering. The angular distribution of radiation was calculated as a sum of radiation from each electron. It is shown that there are nontrivial angular distributions of the emitted photons, which is connected to the superposition of the coherent scattering of electrons by atomic rows ("doughnut scattering" effect) and the suppression of the radiation due to the multiple scattering effect (similar to the Landau-Pomeranchuk-Migdal effect in an amorphous matter). The orientation dependence of angular distribution of radiation is also analyzed.
