    Calculations of Polarizabilities and their gradients for electron energy-loss spectroscopy

  • Original language description

    We illustrate for a set of small hydrocarbons, CH4, C2H4, C3H6 and C3H8, the important role of the electric dipole polarizability tensor and its geometric derivatives in theoretical models of electron energy-loss spectra (EELS). The coupled cluster linear response method together with Sadlej's polarized valence triple zeta basis set of atomic orbitals were used to calculate the polarizabilities and polarizability gradients. Incorporation of these ab initio data into the discrete momentum representationmethod (DMR) leads to perfect agreement between theory and collision experiments.

    Výpočty polarizovatelnosti a jejích geometrických derivací v teoretickém modelu spektroskopie ztrát energie elekronů (electron energy loss)

  • Czech description

    Na sérii malých uhlovodíků CH4, C2H4 a C3H8 , jsme ukázali důležitou roli tenzoru elekrické dipólové polarizovatelnosti a jeho geometrických derivací v teoretickém modelu spektroskopie ztrát energie elekronů (electron energy loss). Molekulové vlastnostibyly počítány metodou lineární odezvy na úrovni sdružených svazků (coupled clusters) se Sadlejovou bází atomových orbitalů. Zahrnutí ab initio dat do DMR (discrete momentum representation) modelu vede k dokonalé shodě teorie a srážkových experimentů.
