  • Minenko, Maksym; Vetter, Martin; Brodyanski, Alexander P.; Jodl, Hans J. (Физика низких температур, 2000)
    The matrix isolation technique is traditionally used to investigate the properties of the matrix-isolated species themselves or to solve some special questions of the theory of defects in solid. We showed here that the ...
  • Chaabouni, H.; Schriver-Mazzuoli, L.; Schriver, A. (Физика низких температур, 2000)
    Fourier transform infrared (FTIR) spectroscopy is used to study the vibrational spectrum of ozone trapped in amorphous ice (a situation observed on icy satellites in the solar system). Evaporation of ozone from ice is ...
  • Chabbi, H.; Dahoo, P.R.; Dubost, H.; Gauthier-Roy, B.; Vasserot, A.-M.; Abouaf-Marguin, L. (Физика низких температур, 2000)
    Vibrational stimulated emissions of CO₂ trapped in low temperature argon matrices have been found experimentally not only in the 16 mm region (v₂ manifold) but also at 10 mm (v₃ - v₁ transition) in the double trapping site ...
  • Misochko, Eugenii Ya.; Goldschleger, Ilya U.; Akimov, Alexander V.; Wight, Charles A. (Физика низких температур, 2000)
    Mobile F atoms react with NH₃ molecules in an argon matrix at temperatures T=7–35 K. The open-shell NH₂–HF complex was observed by EPR and infrared spectroscopies as the main product of this reaction. The hyperfine constants ...
  • Andrews, Lester; Zhou, Mingfei; Chertihin, George V.; Bare, William D.; Hannachi, Yacine (Физика низких температур, 2000)
    Laser-ablated aluminum atoms react with dinitrogen on condensation at 10 K to form N₃ radicals and the subject molecules, which are identified by nitrogen isotopic substitution, further reactions on annealing, and comparison ...
  • Caspary, Nico; Savchenko, Elena V.; Thoma, Anton; Lammers, Andreas; Bondybey, Vladimir E. (Физика низких температур, 2000)
    Optical absorption and laser-induced fluorescence (LIF) spectra of CuO₂ in solid matrices are investigated, and previous visible studies are extended into the infrared. Several new electronic states are observed and their ...
  • Fang, Li; Chen, Xiaoyu; Shen, Xiaole; Liu, Yifei; Lindsay, D.M.; Lombardi, John R. (Физика низких температур, 2000)
    The absorption and resonance Raman spectra of yttrium dimers (Y₂) in argon matrices are measured for the first time. The absorption spectrum (scattering depletion spectrum SDS) shows a weak, broad transition centered near ...
  • Kerins, Paul; Healy, Brendan; McCaffrey, John G. (Физика низких температур, 2000)
    Previous steady-state and time-resolved luminescence spectroscopy of 3p ¹P₁ atomic magnesium, isolated in thin film samples of the solid rare gases, has been extended to include the higher energy 4p ¹P₁ excitation. Well ...
  • Dudkin, V.V.; Gorodilov, B.Ya.; Krivchikov, A.I.; Manzhelii, V.G. (Физика низких температур, 2000)
    The thermal conductivity of CH₄–Kr solid solutions is investigated at CH₄ concentrations 0.2–5.0% in the temperature range 1.8–40 K. It is found that the temperature dependence of the thermal conductivity has features ...
  • Freiman, Yu.A.; Tretyak, S.M.; Jeżowski, A. (Физика низких температур, 2000)
    The magnetic properties of oxygen pair clusters are investigated theoretically for different cluster geometries which can be realized by doping molecular cryomatrices with oxygen. Anomalous temperature and pressure behavior ...
  • Lorenz, Martin; Bondybey, Vladimir E. (Физика низких температур, 2000)
    Infrared and visible absorption spectra and laser-induced fluorescence (LIF) and excitation spectra are obtained for several simple cations deposited from a mass-selected ion beam. In the present preliminary study we ...
  • Bondybey, V.E.; Savchenko, E.V. (Физика низких температур, 2000)
  • Chergui, M. (Физика низких температур, 2000)
    We review some of our works on the absorption, excitation and emission spectra of C₆₀ embedded in rare gas matrices while stressing the role of the environement. The gas phase resonant two-photon ionization spectrum of C₆₀ ...
  • Kiselev, S.I.; Khmelenko, V.V.; Lee, D.M. (Физика низких температур, 2000)
    The observed features of the attenuation of ultrasound in Im–He samples created after the introduction of impurity particles (D₂,N₂, Ne, Kr) in a volume of helium II show that a porous substance consisting of a loosely ...
  • Ganshin, A.; Grigor`ev, V.; Maidanov, V.; Mikhin, N.; Penzev, A.; Polev, A.; Rudavskii, E.; Rybalko, A. (Физика низких температур, 2000)
    A study is made of the kinetic properties of the quantum systems formed in dilute solid mixtures of ³He in ⁴He at ultralow temperatures as a result of the first-order phase transition known as phase separation. The system ...
  • Danilychev, A.V.; Apkarian, V.A.; Kajihara, H.; Tanaka, S.; Koda, S. (Физика низких температур, 2000)
    Atomic oxygen is photogenerated in solid D₂ by 193 nm irradiation of samples initially doped with molecular oxygen. The atoms are detected by laser induced fluorescence over the O(¹S→¹D) transition, which occurs at 559 nm, ...
