  1. 1. Influence of non-dipole transitions on the extraction of EMCD

    University essay from Uppsala universitet/Materialteori

    Author : Paul Michel Zeiger; [2019]
    Keywords : ;

    Abstract : ELNES-spectra of the L3 and L2-edge of bcc-iron are simulated using a Bloch wave method for the calculation of the DDSCS within a 1st-order Born approximation of the inelastic electron scattering process in order to study the influence of non-dipole terms on the EMCD-signal. The necessary electronic structure information is obtained from a DFT-calculation using WIEN2k. READ MORE

  3. 2. Shape functions in calculations of differential scattering cross-sections

    University essay from Institutionen för fysik och astronomi

    Author : Anders Johansson; [2010]
    Keywords : Differential cross-sections; DDSCS; EELS; ELNES; EMCD; Dynamical diffraction theory; thickness function; shape function; shape amplitude;

    Abstract : Two new methods for calculating the double differential scattering cross-section (DDSCS) in electron energy loss spectroscopy (EELS) have been developed, allowing for simulations of sample geometries which have been unavailable to earlier methods of calculation. The new methods concerns the calculations of the thickness function of the DDSCS. READ MORE

  4. 3. Trilobites and stratigraphy of the Middle Ordovician Killeröd Formation, Scania, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Kristina Månsson; [1993]
    Keywords : Trilobita; Middle Ordovician; Uhakuan Stage; stratigraphy; correlations; taxonomy; Killeröd Formation; Killeröd; Scania; Sweden; Earth and Environmental Sciences;

    Abstract : The Killeröd Formation ("Bronnii beds or Coscinorrhinus limestone") is a thin, but distinctive formation in the Middle Ordovician, upper Uhakuan Stage, of southeastern Scania, the southernmost province of Sweden. It is about 70 cm thick and consists of alternating grey microcrystalline limestone and blue-grey shaly mudstone. READ MORE
