  2. 1. Neutron Scattering at 96 MeV

    Author : Angelica Öhrn; Jan Blomgren; Robert Haight; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; elastic scattering; inelastic scattering; differential cross section; optical model potential; Wick s limit; angular distribution; pre-equilibrium; Kärnfysik; Physics; Fysik;

    Abstract : Data on elastic scattering of 96 MeV neutrons from 56Fe, 89Y and 208Pb in the angular interval 10-70° are presented. The previously published data on 208Pb have been extended, as a new method has been developed to obtain additional information at the most forward angles. READ MORE

  4. 2. Elastic and Inelastic Electron Tunneling in Molecular Devices

    Author : Mathias Kula; Yi Luo; Alessandro Troisi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; inelastic electron tunneling spectroscopy; IETS; Green s function; scattering; Theoretical chemistry; Teoretisk kemi;

    Abstract : A theoretical framework for calculating electron transport through molecular junctions is presented. It is based on scattering theory using a Green's function formalism. The model can take both elastic and inelastic scattering into account and treats chemical and physical bonds on equal footing. READ MORE

  6. 4. Jet Production and Parton Dynamics in Deep Inelastic Scattering

    Author : Mattias Davidsson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; DIS; ep scattering; HERA; H1; jets; small-x; Parton Dynamics; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2001:Davidsson;

    Abstract : Hard QCD processes have been studied by measuring the di-jet event rate for deep inelastic scattering in the kinematic range 5 < Q2 < 100 GeV2 and 10-4 < x < 10-2. The jets we re reconstructed using the cone algorithm in the hadronic center-of-mass frame in which the transverse momentum of the jets were required to be greater than 5 GeV. READ MORE

  7. 5. Coupled electron-nuclear dynamics in inelastic X-ray scattering

    Author : Rafael Carvalho Couto; Victor Kimberg; Piero Decleva; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray spectroscopy; resonant inelastic X-ray scattering; water; carbon monoxide; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : This Thesis is devoted to theoretical and experimental studies of resonant inelastic X-ray scattering (RIXS) of carbon monoxide and water molecules. Using state-of-the-art ab initio electronic structure calculations and a time-dependent wave packet formalism, we make a complete analysis of the experimental RIXS spectra of the two molecular systems.
