  • Application of evolutionary algorithms for the model-free determination of scattering matrix and the numerical diagonalization of Nilsson-model Hamiltonian 
    Vodin, A.N.; Korda, V.Yu.; Dovbnya, A.N.; Molev, A.S.; Korda, L.P. (Вопросы атомной науки и техники, 2004)
    A new model-free approach for analyzing the intermediate-energy light nucleus-nucleus elastic-scattering differential cross-sections is proposed to extract the numerical dependencies of S-matrix modulus and nuclear phase ...
  • Bremsstrahlung in alpha-decay: angular analysis of spectra 
    Maydanyuk, S.P.; Belchikov, S.V. (Вопросы атомной науки и техники, 2004)
    A quantum mechanical method of calculation of bremsstrahlung spectra in alpha-decay of heavy nuclei with taking into account an angle between directions of the alpha-particle motion and the photon emission is presented. ...
  • Electroexcitation of giant resonances in ⁵⁴Fe and ⁵⁶Fe nuclei 
    Khvastunov, V.M.; Denyak, V.V.; Ranyuk, Yu.N. (Вопросы атомной науки и техники, 2004)
    The investigation of giant multipole resonanсes in ⁵⁴Fe and ⁵⁶Fe nuclei has been carried out. The resonance at excitation energy of~13 MeV (51A¹/³) is shown to be of E2 type and to exist in both nuclei. In both nuclei the ...
  • Nature of isovector l-forbidden M1 transitions in light nuclei 
    Vodin, A.N.; Ushakov, I.V.; Korda, L.P.; Lepyoshkina, O.A.; Trotsenko, S.A. (Вопросы атомной науки и техники, 2004)
    Systematization of existing experimental data on probabilities of l-forbidden M1 transitions observed in the γ-decay of isobaric analogue resonances in odd-nuclei with A < 52 is carried out. The collective effects, connected ...
  • Observation of ground state of ⁴H in ³H(α,τt)n reaction 
    Gorpinich, O.K.; Povoroznyk, O.M.; Jachmenjov, O.O. (Вопросы атомной науки и техники, 2004)
    In kinematical complete investigation of ³H(α,τt)n reaction by using beam with Eα = 67.2 МеV and titan trituated target the ground state of ⁴Н was observed with Eg.s. = Ent = 3.22 ± 0.25 МеV and Г = 2.9 ± 1,1 МеV.
  • One-dimensional inverse power reflectionless potentials V(x) = const│x-x₀ │⁻ⁿ 
    Maydanyuk, S.P. (Вопросы атомной науки и техники, 2004)
    A condition, at which inverse power one-dimensional potential becomes reflectionless during propagation through it of a plane wave, is obtained on the basis of SUSY QM methods. A scattering of a particle on spherically ...
  • On some problems in describing ⁴He(e,e′) reaction 
    Kuplennikov, E.L.; Nemashkalo, A.A.; Ranyuk, Yu.N (Вопросы атомной науки и техники, 2004)
    Inelastic ⁴He(e,e′) energy spectra and response functions together with realistic calculations are considered. It was found that at the threshold region models predict far less cross section and response functions strength ...
  • On the possibility to observe a heavy Higgs via H⁰ →Z⁰Z⁰ →llνν decays at CMS 
    Levchuk, L.G.; Soroka, D.V.; Sorokin, P.V.; Voronko, M.V.; Zub, S.S. (Вопросы атомной науки и техники, 2004)
    A possibility to observe with the CMS a heavy (MH  200 GeV/c²) Higgs decaying via H⁰ → Z⁰Z⁰ → llνν is studied. It is suggested that for Higgs masses close to threshold of H⁰ decay to the Z⁰Z⁰ pair. The “irreducible” ...
  • Resonance-like structure in ³⁶S(pγ)³⁷Cl reaction 
    Kachan, A.S.; Vodin, A.N.; Kurguz, I.V.; Lepyoshkina, O.A.; Trotsenko, S.A.; Ushakov, I.V (Вопросы атомной науки и техники, 2004)
    The γ-decay of resonances forming resonance-like structure have been investigated in the ³⁶S(pγ)³⁷Cl reaction. The decay schemes have been established for the first time. The branching ratios and probabilities of direct ...
  • Total and partial cross sections of the ¹²С(γ,3α) reaction 
    Afanas’ev, S.N.; Khodyachikh, A.F. (Вопросы атомной науки и техники, 2004)
    The total cross-section of the ¹²С(γ,3α) reaction in the energy range from the threshold to 40 MeV has been measured by the method using a diffusion chamber. It has been established that the two-stage mechanism is dominant: ...
  • Wavelet analysis of inclusive ⁴He(e,e′) spectrum and missing energy spectrum in reaction ¹²С(γ,p)¹¹В 
    Omelaenko, A.S. (Вопросы атомной науки и техники, 2004)
    We demonstrated that the standard contour plot of the wavelet transform with wavelet “Mexican Hat” of the inclusive ⁴He(e,e′) spectrum and missing energy spectrum in reaction ¹²C(γ,р)¹¹B does not give reliable visual ...
