The present PhD thesis includes three different projects which belong to the domain of inner-shell atomic physics and high energy resolution X-ray spectroscopy. The first project consists of a series of in-house measurements of the characteristic K and L X-ray absorption spectra (XAS) of several 3d, 4d and 5d transition metals. For this project the target chamber of the von Hamos curved crystal...

Le but de ce travail est d’évaluer la rentabilité et le potentiel des installations photovoltaïques afin de voir si cette technologie peut remplacer le nucléaire en Suisse. Après avoir présenté les concepts de bases relatifs à l’énergie électrique d’origine solaire, j’ai détaillé la situation suisse et introduit brièvement la situation allemande afin d’observer les...

The broad aim of the present work was to improve our understanding of dissociative electron attachment (DEA) processes mediated by Feshbach resonances. DEA represents an important class of processes leading to electron-driven chemical change. Depending on the nature of the resonance (the transient negative ion) which mediates it, DEA processes can be divided into several types. Out of these, the...

Lifetimes of levels below 4 MeV in ¹¹²Cd have been measured using the Doppler shift attenuation technique following inelastic scattering of monoenergetic neutrons. Reduced transition rates are determined using the results of previous studies and the current lifetimes. The electromagnetic properties of ¹¹²Cd are outlined, and together with results from previous nucleon-transfer studies and...

The protozoon parasite Trypanosoma brucei is the causing agent of human sleeping sickness. Besides its clinical importance T. brucei is also an excellent model for basic research since it has many unique features. The mitochondrion of T. brucei, for example, lacks tRNA genes. The tRNAs required for mitochondrial translation are therefore encoded in the nucleus and imported from the cytosol [1]....

Three different parts related to experimental Atomic Physics are contained in the present Ph. D. thesis. In the three projects the measurements were performed by means of high-resolution x-ray spectroscopy, using a reflecting von Hamos-type bent crystal spectrometer. This experimental technique represents thus the common denominator of the three projects. The two first parts of the thesis are...

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...

The study of nuclear structure is one of the research domains in nuclear physics which have known an important development. It has asked a great effort for the experimenters as well as the theoreticians to study in detail the nuclear many-body problem. In the framework of this thesis, we have tested several nuclear models for two nuclei: 110Cd and 114Te. This choice has not been made at random....
