  3. 3. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

    Detta är en avhandling från Stockholm : KTH

    Författare :Olof von Hofsten; KTH.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. LÄS MER

    Sammanfattning : This thesis summarizes the present status of the nanofabrication of diffractive optics, i.e. zone plates, and test objects for soft x-ray microscopy at KTH. The emphasis is on new and improved fabrication processes for nickel and germanium zone plates. LÄS MER

  5. 5. Solving the quantum scattering problem for systems of two and three charged particles

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Mikhail Volkov; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scattering theory; three body scattering; NATURAL SCIENCES Physics Atomic and molecular physics; NATURVETENSKAP Fysik Atom- och molekylfysik; NATURAL SCIENCES Physics Other physics Mathematical physics; NATURVETENSKAP Fysik Övrig fysik Matematisk fysik; fysik; Physics;

    Sammanfattning : A rigorous formalism for solving the Coulomb scattering problem is presented in this thesis. The approach is based on splitting the interaction potential into a finite-range part and a long-range tail part. In this representation the scattering problem can be reformulated to one which is suitable for applying exterior complex scaling. LÄS MER
