    Optical magnetic resonance tomography and laser spectroscopy of cesium atoms trapped in solid helium

    Nettels, Daniel ; Weis, Antoine (Dir.) ; Dousse, Jean-Claude (Codir.) ; Wynands, Robert (Codir.)

    Thèse de doctorat : Université de Fribourg, 2003 ; no 1432.

    The present thesis has resulted from my research work carried out at the University of Bonn and at the University of Fribourg. The thesis can be roughly divided into two distinct parts, which reflect the research carried out in both places. In Bonn I worked on optical magnetic resonance tomography of atoms in the gas phase, while all of my time in Fribourg was devoted to study specific problems...

    Laser-pumped cesium magnetometers for the PSI-nEDM experiment

    Gröger, Stephan ; Weis, Antoine (Dir.) ; Dousse, Jean-Claude (Codir.) ; Daum, Manfred (Codir.)

    Thèse de doctorat : Université de Fribourg, 2005 ; Nr. 1487.

    This thesis work describes the development of a high resolution magnetic field sensor for a fundamental research project of an international collaboration with participation of the Fribourg Atomic Physics Group. The goal of the collaboration is an experiment searching for an electric dipole moment of the neutron (nEDM), d, which will be performed at Paul Scherrer Institute (PSI). The possible...

    Gamma-ray spectroscopy using the (n,γ) and (α,2nγ) reactions

    Genilloud, Laurent ; Jolie, Jan (Dir.) ; Dousse, Jean-Claude (Codir.)

    Thèse de doctorat : Université de Fribourg, 2000 ; no 1314.

    One of the goals of gamma-ray spectroscopy is to study the structure of the atomic nuclei. To this aim, the nucleus has to be brought into excited states by a nuclear reaction. The study of the subsequent electromagnetic decay via the measurement of γ rays then allows one to establish the level scheme of the atomic nucleus. The comparison of this scheme with a theoretical model allows a better...
