Parametric X-Ray radiation in natural crystals is well known [1-4]. The similar radiation mechanism arises when a charged particle moves in a photonic crystal [5, 6].
Quasi-Cherenkov parametric radiation in a photonic crystal is considered. The expressions for spectral-angular distribution of quasi-Cherenkov radiation emitted by a relativistic particle traversing a photonic crystal are...

One of the important problems in today’s astrophysics and gamma–astronomy is the construction of detectors for high energy photons (more than 1GeV) with the high angle resolution. In this energy range the dominating effect in interaction of photons with matter is e-e+ pair production.The high angle resolution may be achieved using single crystals as an effective converter of photons into...

The difference in angular distributions of the standard Parametric X-Radiation (PXR) from plane-wave electrons (without channeling) and Parametric X-Radiation from channeled electrons (PXRC) is connected with manifestation of two quantum effects: formfactors of transverse quantum channeling states and their initial populations. In the present work we showed that this difference has non-trivial...

In the present work the theory of ultra relativistic electron-positron pair ionization loss in thin plate, situated on different distances from the substance in which the pair is created (which corresponds to the experimental situation of [1]) is developed. It is shown that in this case the transition radiation which occurs during the pair emission from substance may significantly influence...
