Eikonal Approximation and the Conical Effect in Smith-Purcell Radiation
V. V. Syshchenko, A. I. Tarnovsky
The diffraction and transition radiation under normal incidence of a particle to the semi-infinite dielectric plate had been considered previously using the eikonal approximation i…
Regular and Chaotic Motion Domains in the Channeling Electron's Phase Space and Mean Level Density for Its Transverse Motion Energy
N. F. Shul'ga, V. V. Syshchenko, A. I. Tarnovsky +2
The motion of charged particles in a crystal in the axial channeling regime can be both regular and chaotic. The chaos in quantum case manifests itself in the statistical propertie…
Diffraction and Smith-Purcell radiation on the hemispherical bulges in a metal plate
V. V. Syshchenko, E. A. Larikova, Yu. P. Gladkih
The radiation resulting from the uniform motion of a charged particle near a hemispheric bulge in a metal plane is considered. The description of the radiation process based on the…
Radiation of non-relativistic particle on a conducting sphere and a string of spheres
N. F. Shul'ga, V. V. Syshchenko, E. A. Larikova
The radiation arising under uniform motion of non-relativistic charged particle by (or through) perfectly conducting sphere is considered. The rigorous results are obtained using t…
Structure of the channeling electrons wave functions under dynamical chaos conditions
N. F. Shul'ga, V. V. Syshchenko, A. I. Tarnovsky +1
The stationary wave functions of fast electrons axially channeling in the silicon crystal near [110] direction have been found numerically for integrable and non-integrable cases,…
On spectral method in the axial channeling theory
N. F. Shul'ga, V. V. Syshchenko, V. S. Neryabova
The quantization of the transverse motion energy in the continuous potentials of atomic strings and planes can take place under passage of fast charged particles through crystals.…
Incoherent bremsstrahlung in flat and bent crystals
N. F. Shul'ga, V. V. Syshchenko, A. I. Tarnovsky
Incoherent bremsstrahlung by high-energy particles in crystal is due to the thermal spread of atoms in relation to their equilibrium positions in the lattice. The simulation proced…
Contribution of incoherent effects to the orientation dependence of bremsstrahlung from rapid electrons in crystal
N. F. Shul'ga, V. V. Syshchenko, A. I. Tarnovsky
The bremsstrahlung cross section for relativistic electrons in a crystal is split into the sum of coherent and incoherent parts (the last is due to a thermal motion of atoms in the…
On the motion of high-energy wave packets and the transition radiation by "half-bare'' electron
N. F. Shul'ga, V. V. Syshchenko, S. N. Shul'ga
The problem of the motion of high-energy wave packets combined of free electromagnetic waves is considered. It is demonstrated that the transformation of such packets to the packet…
Transition radiation on semi-infinite plate and Smith-Purcell effect
N. F. Shul'ga, V. V. Syshchenko
The Smith-Purcell radiation is usually measured when an electron passes over the grating of metallic stripes. However, for high frequencies (exceeding the plasma frequency of the g…
Incoherent bremsstrahlung in flat and bent crystal
N. F. Shul'ga, V. V. Syshchenko, A. I. Tarnovsky
The bremsstrahlung cross section for relativistic electrons in a crystal is split into the sum of coherent and incoherent parts (the last is due to a thermal motion of atoms in the…
