  • About the possibility to measure the circular polarization of high-energy photon in reaction γ + e⁻ → e⁺ + e⁻ + e⁻ 
    Gakh, G.I.; Konchatnij, M.I.; Levandovsky, I.S.; Merenkov, N.P. (Вопросы атомной науки и техники, 2012)
    Two possibilities of the measuring high-energy photon circular polarization by means of the process γ + e⁻ → e⁺ + e⁻ + e⁻ are investigated. The first one is connected with the measurement of polarization asymmetry of the ...
  • Aharonov-Bohm effect: analysis of scattering in the forward direction 
    Vlasii, N.D. (Вопросы атомной науки и техники, 2012)
    The long-standing problem of a divergent behaviour of the Aharonov-Bohm scattering amplitude in the forward direction is reconsidered. We show that this divergence has no physical consequences, being an artefact of the ...
  • Aharonov-Bohm effect in scattering of high-energy particles 
    Sitenko, Yu.A.; Vlasii, N.D. (Вопросы атомной науки и техники, 2012)
    Quantum-mechanical scattering of coherent high-energy charged particles by a magnetic vortex is considered. The vortex core is assumed to be impermeable to scattered particles, and effects of its transverse size are taken ...
  • Classification of p¯+ p induced reactions 
    Dbeyssi, A.; Tomasi-Gustafsson, E. (Вопросы атомной науки и техники, 2012)
    Annihilation cross sections of antiproton-proton into hadronic channels are studied and related experimental data are compiled. These channels constitute a high source of background to the annihilation reactions p¯+ p → ...
  • Compton mechanism of W and Z boson hadroproduction 
    Bondarenco, M.V. (Вопросы атомной науки и техники, 2012)
    It is argued that W/Z boson production in ultra-relativistic pp collisions in the fragmentation region, subject to a kinematic cut on the boson transverse momentum Q┴ > Q┴min, with 1 GeV/c << Q┴min, << MW/Z, must be dominated ...
  • Electron-positron pair photo-production with radiation of a photon in magnetic field at nonresonant regime 
    Fomin, P.I.; Kholodov, R.I. (Вопросы атомной науки и техники, 2012)
    Theoretical investigations of quantum electrodynamic processes in strong magnetic field are carried out. Such the processes may occur between colliding heavy ions. Magnetic fields of the nuclei are added and electric fields ...
  • Evolution of the hadronic system created in relativistic heavy-ion collisions 
    Anchishkin, D.V.; Muskeyev, A.O.; Vovchenko, V.Yu.; Yezhov, S.N. (Вопросы атомной науки и техники, 2012)
    Evolution of the hadronic system in heavy-ion collisions is studied with the reaction density. The three-dimensional reaction zones and their projections for different types of hadronic reactions are calculated for AGS and ...
  • Gamma radiation of pulsars as result of inverse compton scattering at acceleration of electrons in a pulsar polar gap 
    Flanchik, A.B.; Kontorovich, V.M. (Вопросы атомной науки и техники, 2012)
    A gamma radiation from pulsars due to inverse Compton scattering of coherent low-frequency radiation on relativistic electrons in a polar gap have been considered. The radio emission in the gap arises due to sub relativistic ...
  • 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 ...
  • Polarization effects in elastic proton-electron scattering 
    Gakh, G.I.; Dbeyssi, A.; Marchand, D.; Bytev, V.V.; Tomasi-Gustafsson, E. (Вопросы атомной науки и техники, 2012)
    Proton elastic scattering from electrons at rest is calculated in the Born approximation. The interest of this reaction is related to the possibility of polarizing high energy antiproton beam and to high energy proton ...
  • Polarized photon emission from relativistic planar channeled positrons in crystal 
    Shatnev, M.G. (Вопросы атомной науки и техники, 2012)
    Radiation emitted from high-energy planar channeled positrons in crystal is studied in the framework of quantum electrodynamics to calculate the polarization characteristics of this radiation. Under our approach the general ...
  • The miscut angle influence on the future LHC crystal based collimation system 
    Tikhomirov, V.V.; Sytov, A.I. (Вопросы атомной науки и техники, 2012)
    The paper concerns the future LHC crystal based collimation system. The dependence of collimation efficiency on the muscut angle characterizing nonparallelity of the channeling planes and crystal surface is mainly addressed. ...
  • 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 ...
  • Threshold electron-positron pair production by a polarized electron in a strong magnetic field 
    Novak, O.P.; Kholodov, R.I. (Вопросы атомной науки и техники, 2012)
    Resonant e⁺e⁻–-pair production by an electron in a magnetic field near the process threshold is analytically studied. Using the Nikishov's theorem we estimate the number of events in the magnetic field equivalent to laser ...
