Channeling Radiation & Related Phenomena
The time evolution of parametric X-Ray radiation (PXR) and Diffracted Channeling X-Ray Radiation (DCR) produced by a relativistic charged particle passing through a crystal is studied. Formulas describing this processes are derived.
It is shown that the conditions can be realized under which parametric X-ray radiation and DCR lasts much longer than the particle flight time through the...

Channeling Radiation & Related Phenomena
The experimental results on radiation of (4-16) GeV positrons channeled between the diamond crystallographic planes have been compared with theories without taking into account the medium polarization in many works. Recently it has been developed the corresponding theory taking into account the density effect, and it has been carried out comparison with the experimental data only at 4 GeV and...

Channeling Radiation & Related Phenomena
The photon emission of a quantum channeled particle, accompanied by a plasmon excitation in a crystal target is considered. It is taken into account that the plasmon energy in the crystal is of the same order with the depth of the potential well in which the channeled particle moves . A weak dispersion of the plasmons in the crystal is taken into account, which leads to the selection of the...
