  • 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 ...
  • 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 ...
  • Formation of (Xe2H)* centers in solid Xe via recombination: nonstationary luminescence and «internal electron emission» 
    Savchenko, E.V.; Khyzhniy, I.V.; Uyutnov, S.A.; Gumenchuk, G.B.; Ponomaryov, A.N.; Beyer, M.K.; Bondybey, V.E. (Физика низких температур, 2010)
    The formation of excimers (Xe2H)* in solid Xe doped with molecular hydrogen under electron beam is studied using the original two-stage technique of nonstationary (NS) cathodoluminescence (CL) in combination with the current ...
  • Optically-stimulated desorption of «hot» excimers from pre-irradiated Ar solids 
    Gumenchuk, G.B.; Khyzhniy, I.V.; Ponomaryov, A.N.; Bludov, M.À.; Uyutnov, S.À.; Belov, A.G.; Savchenko, E.V.; Bondybey, V.E. (Физика низких температур, 2008)
    Electronically-induced desorption from solid Ar pre-irradiated by a low-energy electron beam was investigated by activation spectroscopy methods—photon-stimulated exoelectron emission and photon-stimulated luminescence ...
  • Oxygen-driven relaxation processes in pre-irradiated Ar cryocrystals 
    Savchenko, E.V.; Belov, A.G.; Gumenchuk, G.B.; Ponomaryov, A.N.; Bondybey, V.E. (Физика низких температур, 2006)
    Relaxation processes in oxygen-containing Ar cryocrystals pre-irradiated by low-energy electrons are studied with the focus on the role of diffusion controlled atom-atom recombination reaction of oxygen in the relaxation ...
  • Photon-stimulated recombination of self-trapped holes with electrons in pre-irradiated solid Ar 
    Gumenchuk, G.B.; Bludov, M.A.; Belov, A.G. (Физика низких температур, 2005)
    Spatially separated stable charge centers – trapped electrons and self-trapped holes – are generated in Ar cryocrystals by a low-energy electron beam. A combination of the cathodoluminescence and photon-stimulated ...
  • Relaxation channels and transfer of energy stored by pre-irradiated rare gas solids 
    Savchenko, E.V.; Khyzhniy, I.V.; Uyutnov, S.A.; Gumenchuk, G.B.; Ponomaryov, A.N.; Bondybey, V.E. (Физика низких температур, 2009)
    The processes of energy relaxation in rare gas solids pre-irradiated with an electron beam are discussed. We studied the emission of exoelectrons and photons from RGS. Investigations were performed by a set of activation ...
  • Stimulated by laser light exoelectron emission from solid Ar pre-irradiated by an electron beam 
    Gumenchuk, G.B.; Ponomaryov, A.N.; Belov, A.G.; Savchenko, E.V.; Bondybey, V.E. (Физика низких температур, 2007)
    Spatially separated stable charge centers, self-trapped holes and trapped electrons, were generated in Ar cryocrystals by a low-energy electron beam. A combination of the cathodoluminescence (CL) and photon- stimulated ...
  • Thermoactivation spectroscopy of solid Ar doped with N₂ 
    Ponomaryov, A.N.; Savchenko, E.V.; Gumenchuk, G.B.; Khizhniy, I.V.; Frankowski, M.; Bondybey, V.E. (Физика низких температур, 2007)
    A new modification of low-temperature activation spectroscopy technique for real-time correlated study of relaxation processes in cryogenic solids was developed. This enabled us to measure simultaneously thermally stimulated ...
