Quantization of transverse energy levels for planar channeled relativistic electrons together with crystal dispersion may drastically change Cherenkov radiation resulting in mixed Cherenkov-Channeling Radiation (ChCR). In this work we have developed

The computer simulations of the angular distributions of low-Z relativistic isotopes channeled in a half-wavelength-crystal (HWC) revealed that at equal beam energy, crystal thickness and its alignment, the HWC channeling is sensitive to a mass numbe

Here we report on the first measurements of 255 MeV electron scattering by an ultrathin 0.58 μm Si(111) crystal at angles of incidence less than the Lindhard critical angle. Computer simulations of trajectories in the ultrathin crystal explain the a

Detailed experimental studies are performed on the mirroring effect for 255-MeV electrons channeled through a 0.74-μm-thick Si crystal at the injector linac of the SAGA-LS facility. For the planar channeling alignment, deflection of the beam by 0.45

The interaction between a deuterium ion (D+) beam and deuterium-enriched Pd and Ti targets are studied using the HELIS ion accelerator (Lebedev Physical Institute). The neutron yield is determined from the DD reaction in the deuterated Pd target whos

The research for newly developing branch of nuclear physics, the nuclear photonics, has been accompanied since the beginning with the studies on intense MeV photon sources. One of the possible solution is in the use of channeling radiation. The chann

Charged particles channeled in a bent crystal plane are known to be deflected along the bent plane. Such studies have mainly been performed for high-energy positively-charged particles such as protons, and recently for electrons with energies from 85
