Diffraction imaging (topography) with monochromatic synchrotron radiation

New possibilities of diffraction topography at third generation synchrotron radiation facilities

Nuclear Resonant Surface Diffraction of Synchrotron Radiation.

Nuclear resonant x-ray diffraction in grazing incidence geometry is used to determine the lateral magnetic configuration in a one-dimensional lattice of ferromagnetic nanostripes. During magnetic reversal, strong nuclear superstructure diffraction peaks appear in addition to the electronic ones due to an antiferromagnetic order in the nanostripe lattice. We show that the analysis of the angular...

Nuclear Dynamical Diffraction Using Synchrotron Radiation

The scattering of synchrotron radiation by nuclei is extensively explored in this thesis. From the multipole electric field expansion resulting from time-dependent nonrelativistic perturbation theory, a dynamical scattering theory is constructed. This theory is shown, in the many particle limit, to be equivalent to the semi-classical approach where a quantum mechanical scattering amplitude is u...
