  • Symbol calculations the approximate integrals of motion for Hamiltonian systems with N degrees of freedom 
    Bogachev, V.E.; Chekanov, N.A. (Вопросы атомной науки и техники, 2012)
    On the base of the Birkhoff-Gustavson method the algorithm and program in MAPLE for symbol-numerical calculations of the normal form and integrals of motion for resonance and nonresonance Hamiltonian systems with any number ...
  • Symmetry, phase states and dynamics of magnets with spin s=1 
    Kovalevsky, M.Y.; Kotelnikova, O.A. (Вопросы атомной науки и техники, 2012)
    The results of investigations of magnets with spin s=1 are presented. The analysis of the possible symmetry of exchange interactions and its relationship with the magnetic degrees of freedom was done. We formulate the ...
  • The absorption of the variable electric field in superfluid helium by the Аkhiezer mechanism 
    Naumovets, A.S.; Khodusov, V.D. (Вопросы атомной науки и техники, 2012)
    Earlier a series of experiments showed that the energy of a roton in superfluid helium is linearly dependent on electric field. A variable adiabatically changing external electric field leads to a modulation of the roton ...
  • The field dependence of the hopping transport in bond-disordered systems 
    Fateev, M.P. (Вопросы атомной науки и техники, 2012)
    In this report we derive a new version of effective-medium theory for uniform biased diffusion which takes into account both field-created traps and bond disorder. The two random quantities are assumed to be independent. ...
  • The limit solubility relationships based on Frenkel’s heterophase fluctuations theory 
    Shapovalov, R.V.; Osmayev, O.A. (Вопросы атомной науки и техники, 2012)
    For a weak one-component solution, in which the solvent and dissolved substances are not chemically bound, a simple analytical approximation was found for temperature dependence of limiting solubility of the dissolve ...
  • 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. ...
  • Theory of heterogeneous / homogeneous catalytic reaction with presaturation 
    Coeur-Tourneur, C.; Kopiychenko, D.Yu.; Mchedlov-Petrossyan, P.O. (Вопросы атомной науки и техники, 2012)
    In this communication we present a theoretical study of chemical reactions in a system of solid particles, immersed in a fluid environment. Our primary concern here is investigation of the systems of catalytic particles ...
  • 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 problems of the account for energy-momentum conservation law and interference effects at hadron-hadron scattering 
    Sharf, I.V.; Tykhonov, A.V.; Deliyergiyev, M.A.; Sokhrannyi, G.O.; Podolyan, N.A.; Rusov, V.D. (Вопросы атомной науки и техники, 2012)
    We present the new method for the calculation of inelastic scattering cross-section, which doesn't require the use of any additional Regge-like assumptions and accurately accounts for energy-momentum conservation law. This ...
  • 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 ...
  • To the Landau theory of relaxation phenomena in plasma 
    Sokolovsky, A.I.; Gorev, V.N.; Chelbaevsky, Z.Yu. (Вопросы атомной науки и техники, 2012)
    The distribution function of quasi-equilibrium plasma in linear approximation in differences of temperatures and velocities of its components has been obtained. It was done on the basis of our generalization of the ...
  • Transmission of wave packets through open mesoscopic systems 
    Ivanov, N.; Skalozub, V. (Вопросы атомной науки и техники, 2012)
    Tunneling of the wave packets having rectangular and Gaussian forms through a quantum diode is investigated. By using the potential of the system the S-matrix for this structure is obtained and the analytic expressions ...
  • Unusual resonances in superfluid ⁴He – metal double-layer system 
    Nemchenko, K.E.; Rogova, S.Yu. (Вопросы атомной науки и техники, 2012)
    We consider the model of temperature and heat flow evolution in a double-layer system. The first layer is superfluid ⁴He and the second layer is a metallic plate. At the left end of the first layer the oscillating heat ...
  • Vector to pseudoscalar meson radiative transitions in chiral theory with resonances 
    Ivashyn, S.A. (Вопросы атомной науки и техники, 2012)
    The form factor of the vector meson V conversion transition into the pseudoscalar meson Ρ and the lepton pair l⁺l⁻ is presented for V ≡ ρ⁰, ω, φ and Ρ ≡ π⁰, η. Our approach is based on the chiral effective field theory ...
