  • Stepanovsky, Yu.P.; Zanimonskiy, Y.Y. (Вопросы атомной науки и техники, 2007)
    It has been shown some time ago that a neutron undergoes some acceleration in uniform electromagnetic fields. We found an exact solution of Dirac wave equation for a neutron imbedded in a uniform electromagnetic field and ...
  • Sannikov-Proskuryakov, S.S. (Вопросы атомной науки и техники, 2007)
    Closed model of Universe on the earlier stage of its evolution is defined more precisely. It is considered here that after the Big Bang and De Sitter’s (exponential) expanding phase in which the pressure is p=-c²ρc (see ...
  • 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 ...
  • Kontorovich, V.M. (Вопросы атомной науки и техники, 2007)
    The pulse sequence is interpreted as a realization of a random electron discharge process in a vacuum gap over the polar cap (PC) —the open magnetic force line region on the neutron star surface. This point of view is ...
  • 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 ...
  • Gazazian, E.D.; Guidi, V.; Ispirian, K.A.; Ispirian, M.K.; Kalantaryan, D.K. (Вопросы атомной науки и техники, 2007)
    The equations of motion of electrons in a plane monochromatic wave with linear, circular and elliptical polarizations are solved taking into account the initial conditions. The cases when the interaction of the electrons ...
  • Filippov, G.M. (Вопросы атомной науки и техники, 2007)
    The new perturbation theory in QED without the ultraviolet catastrophe is constructed.
  • Yaremko, Yu. (Вопросы атомной науки и техники, 2007)
    A renormalization scheme which relies on energy-momentum and angular momentum balance equations is applied to the derivation of effective equation of motion for a massless point-like charge. Unlike the massive case, the ...
  • Konchatnij, M.I.; Merenkov, N.P. (Вопросы атомной науки и техники, 2007)
    Radiative corrections (RC) to the differential and total Compton scattering cross sections are calculated. We consider the scattering of photon with a few GeV energy by the atomic electron. The reason is the unique possibility ...
  • Fomin, P.I.; Kholodov, R.I. (Вопросы атомной науки и техники, 2007)
    The quantum-electrodynamic process of electron-positron pair production by a photon is considered in a strong external magnetic field. The process is accompanied by emission of the final photon. Kinematics and resonance ...
  • Voroshilo, O.I.; Roshchupkin, S.P. (Вопросы атомной науки и техники, 2007)
    We present, for general relativistic case, a theoretical investigation of the resonant two-photon emission of an electron in the circularly-polarized electromagnetic wave. Resonances are related to a virtual intermediate ...
  • Sannikov-Proskuryakov, S.S. (Вопросы атомной науки и техники, 2007)
    We continue consideration of physical characteristics of early Universe. Here our attention is concentrated on the three topics: thermodynamics, relic helium, energy of physical vacuum.
