  • 9th International Conference on Cryocrystals and Quantum Crystals 
    Strzhemechny, M.A.; Yakub, E.S. (Физика низких температур, 2013)
  • Anomalous low-temperature “post-desorption” from solid nitrogen 
    Savchenko, E.V.; Khyzhniy, I.V.; Uyutnov, S.A.; Ponomaryov, A.N.; Gumenchuk, G.B.; Bondybey, V.E. (Физика низких температур, 2013)
    Anomalous low-temperature post-desorption (ALTpD) from the surface of nominally pure solid nitrogen pre-liminary irradiated by an electron beam was detected for the first time. The study was performed using a combi-nation ...
  • Cascade units for neon isotopes production by rectification method 
    Bondarenko, V.L.; Simonenko, Yu.M.; Diachenko, O.V.; Matveyev, E.V. (Физика низких температур, 2013)
    Basics of neon separation into isotopes by distillation method at T = 28 K are discussed. The required numbers of transfer units of the top and bottom column sections at different loads are calculated. The experimental ...
  • Cluster approach to formation of nitrogen–rare gas cryoalloys 
    Solodovnik, A.A.; Danchuk, V.V.; Mysko, N.S. (Физика низких температур, 2013)
    Structure of solid binary N₂–Kr and N₂–Ar solutions were studied by transmission electron diffraction (THEED). The samples were prepared in situ by deposition of gaseous mixture onto an Al substrate cooled to 20 K. The ...
  • Comparative study of thermostimulated luminescence and electron emission of nitrogen nanoclusters and films 
    Boltnev, R.E.; Bykhalo, I.B.; Krushinskaya, I.N.; Pelmenev, A.A.; Khmelenko, V.V.; Lee, D.M.; Khyzhniy, I.V.; Uyutnov, S.A.; Savchenko, E.V.; Ponomaryov, A.N.; Gumenchuk, G.B.; Bondybey, V.E. (Физика низких температур, 2013)
    We have studied thermostimulated luminenscence and electron emission of nitrogen films and nanoclusters containing atomic nitrogen free radicals. Thermostimulated electron emission from N₂ nanoclusters was ob-served for ...
  • Cryogenic electrolytes 
    Nazin, S.; Chikina, I.; Shikin, V. (Физика низких температур, 2013)
    The emphasis is made on experimentally observed indications of the presence of metastable ion dipoles in solid helium. Similar quasiparticles possessing positive scattering length for injected electrons are assumed to exist ...
  • Crystalline and amorphous structure of astrophysical ices 
    Strazzulla, G. (Физика низких температур, 2013)
    The structure of water and other ices strongly depends on the temperature at which they formed, e.g., by vapor deposition. It is amorphous if ices are formed at low temperature (e.g., 10–30 K for water ice), or crystalline if ...
  • Diffusion model of the thermal conductivity plateau of weak solid solutions of neon in parahydrogen 
    Zholonko, N.N. (Физика низких температур, 2013)
    The diffusion kinetic of classic impurity particles has been investigated in the frame of one-dimensional two-level model and applied for the explanation of solid hydrogen thermal conductivity data with extremely low ...
  • Elastic properties of compressed cryocrystals in a deformed atom model 
    Gorbenko, Ie.Ie.; Zhikharev, I.V.; Troitskaya, E.P.; Chabanenko, Val.V.; Pilipenko, E.A. (Физика низких температур, 2013)
    A model with deformed atom shells is built to investigate the elastic properties of rare-gas crystals Ne and Kr under high pressure. It is shown that the observed deviation from the Cauchy relation cannot be adequately ...
  • Energy of vacancy formation in the continuum matter model 
    Khrapak, A.G.; Khrapak, S.A. (Физика низких температур, 2013)
    The quantum energy spectrum of the oscillating spherical void in solids is calculated within the continuum matter model. It is suggested that the ground state of the oscillating void corresponds to the vacancy in real ...
  • Hydrogen at extreme pressures (Review Article) 
    Goncharov, Alexander F.; Howie, Ross T.; Gregoryanz, Eugene (Физика низких температур, 2013)
    Here we review recent experimental and theoretical studies of hydrogen approaching metallization regime. Ex-perimental techniques have made great advances over the last several years making it possible to reach previously ...
  • Ionic model for highly compressed solid hydrogen 
    Yakub, E.S. (Физика низких температур, 2013)
    We propose a simple ionic model for high-pressure conducting phase IV of solid hydrogen observed recently at room temperature. It is based on an assumption of dissociative ionization of hydrogen molecules 3H₂= 2H₂⁽⁺⁾2H⁽⁻⁾ ...

    Konstantinov, V.A.; Sagan, V.V.; Revyakin, V.P.; Zvonaryova, A.V.; Pursky, O.I. (Физика низких температур, 2013)
    Thermal conductivity of solid furan has been measured at isochoric conditions in the high-temperature orien-tationally-disordered phase I for samples of different densities. Our isochoric data show a gradual increase of ...

  • Melting line of polymeric nitrogen 
    Yakub, L.N. (Физика низких температур, 2013)
