Invited talk
Radiation by relativistic electrons in matter, near matter or in external field, from Channeling to Smith-Purcell radiations, are compared regarding
1) the emission mechanisms. Is it direct or via medium polarization? classical or quantum ? target-coherent ? bunch-coherent ? dipole or non-dipole ? in weak or critical QED field ?
2) the radiation qualities: intensity, hardness, line width...

We present an experimental demonstration of a Small Amplitude Short Period (SASP) Crystal Undulator, proposed by A. Kostyuk. Such a device produces MeV radiation from 6-800 MeV electrons, and observed spectra are in good agreement with calculated values.

Usually, results of interaction of relativistic particles with a crystalline deflector are observed as a variation in the angular distribution of the particles. But for recent ten, the understanding of properties of X-ray radiation of relativistic particles moving in a...

In the present paper we investigate the combine effect in CB from axially channelled electrons. To study this combine effect we modified method of virtual photons, taking into account the channelling of the radiating particles.

The influence of the processes electrons capture (or loss) by the high-energy multiply charged ions on the Cherenkov and transition electromagnetic radiation are discussed. Multiply charged ion charge fluctuations in the targets lead to an additional contribution to spectral- angular density of radiation (the correlation effect [1]). If the threshold condition for the occurrence of Cherenkov...

The paper presents a brief background on cold fusion leading to a discussion on some aspects of atomic physics. We are explaining the selection of the only permitted orbitals of deuterium atoms in conducting crystals when saturated with deuterium. Conduction electrons in metallic crystal are grouped in potential niches of the crystal lattice, resulting in a ban for s-states of hydrogen to...
