Abstract

X-ray absorption spectra measured for film of the aligned multiwall carbon nanotubes at different grazing angles of incident beam showed a variation in π*/σ* peak ratio. An average deviation of carbon nanotubes from vertical orientation was estimated from comparison of the experimental data with the results quantum-chemical calculation of (6,6) carbon tube crystal. Total imperfectness of tubes ordering in the film and tube layers packing was found to be about 60°. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

Abstract

We report on excellent results obtained during commissioning of the Russian-German Beamline at bending magnet D16-1A of the electron-storage ring BESSY II. The photoionization spectra taken at the 2,-13 resonance of doubly excited He reveal a resolving power of E/ΔE∼100,000 at hυ=64.12 eV. To our knowledge, this represents the best energy resolution achieved up to now on a bending-magnet beamline in the grazing-incidence photon-energy range. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]
