  • Circular polarization of the high energy electron bremsstrahlung with account of the second Born approximation 
    Shul’ga, N.F.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2007)
    The estimation of contribution of the second Born approximation into circular polarization of bremsstrahlung from linearly polarized electrons is obtained. Account of this contribution could be important for correct ...
  • Eikonal approximation in the transition radiation theory 
    Shul’ga, N.F.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2007)
    Simple variant of eikonal approximation in transition radiation theory is proposed. Spectral-angular density of radiation on fiber-like targets and nanotubes is calculated using Born and eikonal approximations. The conditions ...
  • Electromagnetic wave scattering on a dielectric cylinder in Born approximation 
    Syshchenko, V.V. (Вопросы атомной науки и техники, 2015)
    The scattering of the plane electromagnetic wave on a spatially extended, fiber-lake target is considered. The fomula for the scattering cross section is obtained using the approximation analogous to Born one in quantum mechanics.
  • Incoherent bremsstrahlung in flat and bent crystals 
    Shul'ga, N.F.; Syshchenko, V.V.; Tarnovsky, A.I. (Вопросы атомной науки и техники, 2012)
    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 procedure developed earlier for the incoherent ...
  • Numerical computation of incoherent bremsstrahlung from fast electrons in single crystals 
    Shul’ga, N.F.; Syshchenko, V.V.; Tarnovsky, A.I. (Вопросы атомной науки и техники, 2009)
    The incoherent bremsstrahlung of fast electrons in crystal is caused by thermal spread of atoms from their equilibrium positions in the lattice. Its intensity manifests substantial orientation dependence under angles of ...
  • On the incoherent radiation of relativistic electrons and positrons in crystal 
    Shul’ga, N.F.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2004)
    The incoherent bremsstrahlung of high energy electrons in crystal is caused by thermal spread of atoms from their equilibrium positions in the lattice. In the present article the simulation procedure for the intensity ...
  • Polarization of transition radiation on some sorts of targets 
    Shul’ga, N.F.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2001)
    The problem of transition radiation under impact of relativistic particles under small angle to the atomic string of a crystal is considered. The conditions under which the non-uniformity of the electron density along the ...
  • Spectral method in the quantum theory of axial channeling 
    Shul'ga, N.F.; Syshchenko, V.V.; Neryabova, V.S. (Вопросы атомной науки и техники, 2014)
    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. The energy levels for electron moving in ...
  • Statistical properties of the energy levels in the axial channeling quantum theory 
    Shul'ga, N.F.; Syshchenko, V.V.; Isupov, A.Yu. (Вопросы атомной науки и техники, 2014)
    The energy of transversal motion of relativistic charged particles in the uniform potential of atomic strings of a crystal could be quantized. The energy levels of electrons axially channeled in the system of parallel [110] ...
  • The prewave zone effect in transition radiation and bremsstrahlung by relativistic electron 
    Shul'ga, N.F.; Trofymenko, S.V.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2012)
    The problem of measurement of bremsstrahlung characteristics in the process of sharp scattering of relativistic electron in the case when transverse distances responsible for radiation process have macroscopic size is ...
  • The second Born approximation in theory of bremsstrahlung of relativistic electrons and positrons in crystal 
    Shul’ga, N.F.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2001)
    The formulae for the cross section of bremsstrahlung by relativistic electrons and positrons taking into account the contribution of the second Born approximation are obtained. The dependence of the radiation cross section ...
