  • Diversity and Community Structure of Oribatid Mites (Acari, Oribatei) at Memorial Complexes of a Megapolis 
    Kolodochka, L.A.; Shevchenko, O.S. (Вестник зоологии, 2013)
    In different types of substrate (soil, litter, lichens and mosses) collected at three memorial complexes (cemeteries) of Kyiv (Ukraine), 70 species from 57 genera, 34 families of oribatid mites were found. A few eurytopic ...
  • Excitation of isomer in 115In(γ,γ′) 115mIn reaction 
    Shevchenko, O.S.; Dovbnja, A.N.; Kuplennikov, E.L.; Nemashkalo, A.A.; Noga, V.I.; Ranyuk, Y.N. (Вопросы атомной науки и техники, 2005)
    Activation yield measurements of the 115In(γ,γ′) 115mIn reaction were performed with bremsstrahlung of endpoint energies in the range of Eϒ max ≤ 0.8…3.0 MeV. The integrated cross sections for some intermediate states ...
  • Longliving ¹⁷⁸m²Hf, ¹⁷²Hf, ¹⁵⁰Eu and ¹³³Ba isotopes photoproduction studding 
    Goncharov, I.G.; Dovbnya, A.M.; Ranyuk, Y.M.; Shevchenko, O.S. (Вопросы атомной науки и техники, 2007)
    The yield of the ¹⁷⁸m²Hf (T = 31y), ¹⁷²Hf (1.87), ¹⁵⁰Eu (36.9) and ¹³³Ba (10.5) isotopes was measured after irradiation of a tantalum target with 1.0 GeV Kharkiv linear accelerator electron beam. The integral and average ...
  • Photoexcitation of ⁸⁷mSr by (γ,γ') reaction 
    Shevchenko, O.S.; Ranyuk, Y.M.; Dovbnya, A.M.; Kuplennikov, E.L.; Nemashkalo, A.A.; Goncharov, I.G.; Borysenko, V.N.; Noga, V.I. (Вопросы атомной науки и техники, 2007)
    The photoexcitation of ⁸⁷mSr (energy of isomeric level Eiso = 388.532 keV ) using the gamma rays produced by electron electrostatic accelerator was examined for the bremsstrahlung end-points energy covered the range from ...
  • Species Complexes of the Oribatid Mites (Sarcoptiformes, Oribatei) in Soils of Urban Street Lawns with Different Pollution Rates 
    Shevchenko, O.S.; Kolodochka, L.A. (Вестник зоологии, 2013)
    Species complexes of oribatid mites at six plots on the street lawns in one of Kyiv districts are studied. In total 27 species of 26 genera and 19 families of oribatid mites are found. Direct correlation between oribatid ...
  • Тhermodesorbtion from construction materials irradiated by ions of helium on a linear accelerator 
    Anokhin, R.А.; Dubniuk, S.M.; Zaitsev, B.V.; Pavlii, К.V.; Reshetnikov, V.M.; Shevchenko, O.S. (Вопросы атомной науки и техники, 2018)
    On a linear accelerator samples of alloys of zirconium, molybdenum and stainless steels were irradiated by beams of helium ions with an energy of 0.12…4 MeV. The results of thermal desorption of helium from irradiated samples ...
