    • Angular and temperature dependence of the magnetic circular dichroism in 4d core-level photoemission from Gd(0001) 

      Denecke, Reinhard; Morais, Jonder; Ynzunza, Ramon X.; Fecher, Gerhard H.; Menchero, Jose G.; Liesegang, John; Kortright, Jeff B.; Hussain, Zahid; Fadley, Charles S. (2002) [Journal article]
      We present experimental and theoretical results for the angular and temperature dependence of magnetic circular dichroism in Gd 4d core-level photoelectron emission from a Gd(0001) surface in both normal and off-normal ...

    • Cluster coarsening and luminescence emission intensity of Ge nanoclusters in SiO/sub 2/ layers 

      Lopes, João Marcelo Jordão; Zawislak, Fernando Claudio; Behar, Moni; Fichtner, Paulo Fernando Papaleo; Rebohle, Lars; Skorupa, Wolfgang (2003) [Journal article]
      SiO2 layers 180 nm thick are implanted with 120 keV Ge+ ions at a fluence of 1.2x1016 cm-². The distribution and coarsening evolution of Ge nanoclusters are characterized by Rutherford backscattering spectrometry and ...

    • Coulomb heating of channeled H/sup + sub 2/ and H/sup + sub 3/ molecules in Si 

      Fadanelli Filho, Raul Carlos; Grande, Pedro Luis; Behar, Moni; Dias, Johnny Ferraz; Schiwietz, Gregor; Denton, Cristian D. (2004) [Journal article]
      Si-K x-ray and backscattering yields have been measured as a function of the projectile entrance angle for atomic and molecular (H2 + and H3 +) hydrogen ions channeling at kinetic energies of 150 keV per proton along the ...

    • The temperature of extended gas in active galaxies : evidence for matter-bounded clouds 

      Wilson, Andrew S.; Binette, Luc; Storchi-Bergmann, Thaisa (1997) [Journal article]
      We report measurements of the electron temperature at about a dozen locations in the extended emission-line regions of five active (Seyfert and radio) galaxies. Temperatures (T[O III] and T[N II]) have been determined from ...
