  • Self-sustained regime of nuclear burning wave in U–Pu fast reactor with Pb–Bi coolant 
    Fomin, S.P.; Mel’nik, Yu.P.; Pilipenko, V.V.; Shul’ga, N.F. (Вопросы атомной науки и техники, 2007)
    The regime of the nuclear burning wave in a fast reactor is described using the non-stationary diffusion equation for neutron transport and equations of the fuel component burn-up and of nuclear kinetics for precursor ...
  • Resonant two-photon emission of an electron in the field of an electromagnetic wave 
    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 ...
  • About neutron acceleration in uniform electromagnetic fields 
    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 ...
  • Some problems in the theory of early universe evolution 
    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.
  • Dice and pulsars 
    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 ...
  • Radiative corrections in high energy Compton scattering 
    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 ...
  • Femtosecond scanning, chopping (slicing) and measurement of length of electron bunches by laser pulses: principles of femtosecond oscilloscopes 
    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 ...
  • Resonant photoproduction of e⁺e⁻-pair with photon emission in strong magnetic field 
    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 ...
  • Two consecutive heterogeneous reactions of second order in well mixed aerosol system 
    Kopiychenko, D.Yu.; Mchedlov-Petrossyan, P.O.; Khomenko, G.A. (Вопросы атомной науки и техники, 2007)
    The dynamics of concentration changes in well-mixed systems with two consecutive heterogeneous reactions of the second order on the surface of monodisperse aerosol particles is analyzed in the case of mass transfer ...
  • Nonrelativistic free electron lasers 
    Buts, V.A.; Yegorov, A.M.; Kornilov, E.A.; Marekha, V.I.; Tolstoluzhsky, A.P. (Вопросы атомной науки и техники, 2007)
    The results of the theoretical and experimental investigations of excitation of oscillations by flows of charged particles and its particles dynamics are represented at their motion as in a periodic potential and in a field ...
  • Radiation reaction and renormalization for a photon-like charged particle 
    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 ...
  • About pressure in model of the expanding Universe 
    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 ...
  • Spectral properties of the two-dimensional multiwell potential 
    Chekanov, N.A.; Shevchenko, E.V. (Вопросы атомной науки и техники, 2007)
    Two-dimensional multiwell Hamiltonian system with four local minima is considered. The motion of the system shifts from regular to chaotic through “mixed state”, i.e. the state, when regular and irregular regimes of motion ...
  • Dynamical chaos rise in the system of large number of nonlinear coupled oscillators 
    Buts, V.A.; Kovalchuk, I.K.; Tarasov, D.V. (Вопросы атомной науки и техники, 2007)
    The problem of dynamical chaos arising in distributed systems is considered. It was shown that in many cases it is possible to allocate relatively isolated subsystem which may be simpler for investigation. We suppose that ...
  • The world of chaos 
    Bolotin, Yu.L .; Yanovsky, V.V. (Вопросы атомной науки и техники, 2007)
    The present paper is devoted to discussion of origins of the modern paradigm of deterministic chaos: the transition from the older philosophy understanding chaos as a result of uncontrolled external effects to the theory ...
  • Geometrical approach for description of the mixed state in multi-well potentials 
    Berezovoj, V.P.; Bolotin, Yu.L.; Ivashkevych, G.I. (Вопросы атомной науки и техники, 2007)
    We use the so-called geometrical approach [1] in description of transition from regular motion to chaotic one in Hamiltonian systems with potential energy surface that has several local minima. Distinctive feature of such ...
  • Clothed particle representation in quantum field theory: mass renormalization 
    Korda, V.Yu.; Shebeko, A.V. (Вопросы атомной науки и техники, 2007)
    The method of unitary clothing transformations is applied in the model involving nucleon and neutral pion fields interacting via the regularized pseudoscalar Yukawa-type coupling. In this approach the mass counterterms are ...
