Angular and temperature dependence of the magnetic circular dichroism in 4d core-level photoemission from Gd(0001)
(2002) [Artículo de periódico]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
(2003) [Artículo de periódico]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
(2004) [Artículo de periódico]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
(1997) [Artículo de periódico]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 ...
