Full textDans la première partie de ce manuscrit, nous décrivons, tout d'abord, un spectromètre à cristal courbe et en transmission, couplé à un détecteur germanium sensible en position. Cet ensemble, dédié à la mesure de l'énergie de photons X entre 50 et 100 keV et qui est destiné à être monté sur l'accélérateur du GSI, nous permettra, dans les années avenirs, de gagner un ordre de grandeur sur la précision de la mesure du déplacement de Lamb du niveau fondamental de l'uranium hydrogénoïde, afin de tester la QED en champ coulombien fort. Ensuite, nous détaillons une expérience qui nous permettra de donner bientôt une nouvelle valeur de la masse du pion chargé avec une incertitude relative de 1 ppm. Elle est basée sur une spectroscopie X de l'azote pionique, effectuée au PSI. Pour celle-ci nous utilisons un montage composé d'une trappe anticyclotronique, d'un spectromètre de Bragg en réflexion, possédant un cristal sphérique et d'un détecteur CCD refroidit. Ce dispositif permet également de tester la QCD et la théorie des perturbations chirales, par une mesure des transitions radiatives de l'hydrogène pionique.
La seconde partie est consacrée à une description d'une mesure la durée de vie d'un niveau métastable de l'or héliumoïde, grâce à une expérience de temps de vol, qui se déroule au GSI. Nous donnons, pour la toute première fois pour un Z si élevé, une valeur précise de cette durée de vie, qui constitue un test important de la théorie relativiste à n-corps.

Full textWithin the thesis a new procedure, called "reduction of the functional integral", is developed for formulating quantum field theories in terms of gauge invariant quantities (physical observable fields). It provides a new way for the construction and analysis of effective field theoretical models. Starting with a detailed mathematical analysis of the algebra of Grassmann--algebra valued gauge invariants, the procedure is applied to the two--dimensional Thirring--model, the four--dimensional spinor QED and the one--flavor QCD in four dimensions. For each of these three models an effective theory of interacting bosonic gauge invariant fields was deduced on the quantum level. Apart from this more theoretical considerations, first steps on the way to an analysis of the obtained effective models towards their application in various physical problems are performed. In the case of the two Abelian models a new approach to the bosonisation scheme and the calculation of the chiral anomaly in two and four dimensions were obtained, giving some deeper insight into the nature of the bosonisation phenomenon as well as the nature of anomalies, respectively. Moreover, the investigation of current--current expectation values shows that the suggested procedure can be viewed as a new way towards a non--perturbative formulation and understanding of quantum field theories
