  • 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 ...
  • 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 ...
  • Amplification of volume reflection by crystal axes 
    Tikhomirov, V.V. (Вопросы атомной науки и техники, 2007)
    It is shown that if protons move at small angles with respect to crystal axes which form bent crystal planes the average angle of proton volume reflection from these planes increases several times.

  • Bose-Einstein condensation of particles with spin 
    Peletminskii, A.S.; Peletminskii, S.V. (Вопросы атомной науки и техники, 2007)
    One of possible ground states and low-lying collective modes of Bose-Einstein condensate (BEC) of atoms with arbitrary spin in a magnetic field is studied using Bogoliubov's model for weakly interacting Bose gas. The ...
  • Branes in string theory 
    Sorokin, D.P. (Вопросы атомной науки и техники, 2007)
    We give a simple overview of some basic aspects of the dynamics of branes in string theory and of their role in the attempts to get from String Theory a realistic model of fundamental interactions of elementary particles.
  • Charged and neutral kaon production in electron-positron annihilation 
    Ivashyn, S.A.; Korchin, A.Yu. (Вопросы атомной науки и техники, 2007)
    A model for description of electromagnetic form factors of the charged and neutral kaons in the energy region √s ~ 1-2 GeV is presented. Our approach is based on extended vector-meson-dominance model. It accounts for ...
  • 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 ...
  • Clothed particle representation in quantum field theory: boost generators of the Poincaré group 
    Korda, V.Yu.; Frolov, P.A. (Вопросы атомной науки и техники, 2007)
    The method of the unitary clothing transformations is used to construct the generators of the Poincaré group in the instant form of relativistic dynamics in the second and third orders in the coupling constant. It is shown ...
  • 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 ...
  • Construction of probabilistic solutions of the Boltzmann equation 
    Virchenko, Yu.P.; Karabutova, T.V. (Вопросы атомной науки и техники, 2007)
    The proving method of the Cauchy problem solvability of the Boltzmann kinetic equation with spatially uniform initial data in the case of particle scattering cross-section finiteness is proposed. It is based on the ...
  • Corellation analysis for noise diagnostics of in-core reactor equipment 
    Rudakov, V.A. (Вопросы атомной науки и техники, 2007)
    The brief survey of noise methods of PWR in-core equipment diagnostics is presented. The possibilities of using the standard system of neutron emission sensors and temperature control sensors for registration of noise ...
  • Correlation functions in BCS-BEC transition region of nuclear matter 
    Isayev, A.A. (Вопросы атомной науки и техники, 2007)
    The density, spin and isospin correlation functions in nuclear matter with a neutron-proton (np) condensate are calculated to study the possible signatures of the BEC-BCS crossover in the low-density region. It is shown ...
  • Covariant amplitude decomposition in relativistic fermion scattering problems 
    Bondarenko, M.V. (Вопросы атомной науки и техники, 2007)
    A parameterization of on-mass-shell relativistic fermion scattering amplitudes by a set of 4 covariant amplitudes is proposed, which in the non-relativistic limit turn to coefficients of the matrix amplitude decomposition ...
  • Creation of superfluid helium rotons by a solid’s phonons incident normal to the interface 
    Adamenko, I.N.; Nemchenko, K.E; Tanatarov, I.V. (Вопросы атомной науки и техники, 2007)
    We solve the one-dimensional problem of quasiparticles’ transfer through the interface between a solid and superfluid helium. Superfluid helium is treated as a continuous medium with correlations. When a solid’s phonon is ...
  • Density of states of interacting two-level systems in amorphous solids in the mean random field approximation 
    Borisenko, A.A. (Вопросы атомной науки и техники, 2007)
    The mean random field approach [1,2] is generalized to the case of random (with certain distribution) values of tunneling matrix elements and double-well potential asymmetries and applied to account for the dipole interaction ...
  • 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 ...
  • Direct and inverse scattering on the line for one-dimensional Schrödinger equation 
    Bazargan, J. (Вопросы атомной науки и техники, 2007)
    The direct and inverse scattering problems are studied for one-dimensional Schrödinger equation with a potential, which is asymptotically close to distinct periodic functions on the different half-axes. It is supposed that ...
  • Distinctive numbers of production systems functioning description 
    Pignasty, O.M. (Вопросы атомной науки и техники, 2007)
    The production system of an enterprise is represented as the system with large quantity of elements, which are the objects of one's labour. The distinctive numbers of the production system are introduced by means of ...
