Transition probabilities of 41 transitions originating from the 3d(9)4d and 3d(8)4s(2) electronic configurations of singly ionized copper have been determined using laser-induced breakdown spectroscopy. The Cu II ions have been produced by laser ablation. The experimental relative transition probabilities have been converted into an absolute scale using measured branching fractions and theoretical radiative lifetimes of the corresponding upper states obtained by a relativistic Hartree-Fock method taking core-polarization and configuration interaction effects into account. Comparison of the new results with previously available data is also presented. [less ▲]

Radiative parameters for transitions depopulating the levels belonging to the 3d84s2 configuration of Cu(II) and 4d96s and 4d95d configurations of Ag(II) have been obtained both theoretically and experimentally. On the experimental side, a laser-produced plasma was used as a source of Cu(II) and Ag(II) spectra. The light emitted by the plasma was focused on the input slit of a grating monochromator coupled with a time-resolved optical multichannel analyzer system. Spectral response calibration of the experimental system was made using a deuterium lamp in the wavelength range extending from 200 to 400 nm, and a standard tungsten lamp in the range from 350 to 600 nm. The transition probabilities were obtained using measured branching fractions and available radiative lifetimes of the corresponding states. On the theoretical side, a relativistic Hartree-Fock (HFR) approach, including core-polarization effects, has been used for the calculations. A reasonable agreement theory–experiment has been observed. [less ▲]

Radiative parameters for transitions depopulating the levels belonging to the 4d(8)5s(2), 4d(9)6s and 4d(9)5d configurations of Ag II have been obtained from a combination of theoretical lifetimes and experimental branching fractions. On the experimental side, a laser-produced plasma was used as a source of Ag+ ions. The light emitted by the plasma was analysed by a grating monochromator coupled with a time-resolved optical multichannel analyser system. Spectral response calibration of the experimental system was performed using a deuterium lamp in the wavelength range from 200 to 400 nm, and a standard tungsten lamp in the range from 350 to 600 nm. The transition probabilities were obtained from measured branching ratios and theoretical radiative lifetimes of the corresponding states calculated with a relativistic Hartree-Fock approach including core-polarization effects and configuration interaction in an extensive way. Theoretical and experimental data have been compared and the new data have also been compared with the few previous results available in the literature. [less ▲]

Extending the standard model with three right-handed neutrinos (Nk) and a second Higgs doublet (η), odd under the discrete parity symmetry Z2, Majorana neutrino masses can be generated at one-loop order. In the resulting model, the lightest stable particle, either a boson or a fermion, might be a dark matter candidate. Here we assume a specific mass spectrum (M1≪M2<M3<mη) and derive its consequences for dark matter and collider phenomenology. We show that (i) the lightest right-handed neutrino is a warm dark matter particle that can give a ~10% contribution to the dark matter density; (ii) several decay branching ratios of the charged scalar can be predicted from measured neutrino data. Especially interesting is that large lepton flavor violating rates in muon and tau final states are expected. Finally, we derive upper bounds on the right-handed neutrino Yukawa couplings from the current experimental limit on Br(μ→eγ). [less ▲]

Considerable progress has been recently made in cobalt-mediated radical polymerization (CMRP), a controlled radical polymerization system based on the temporary deactivation of the polymer chains by a cobalt complex, like the improvement of the mechanistic understanding, the extension to a range of monomers and the preparation of novel architectures. However, the real breakthrough in this field concerns the development of efficient radical coupling methods for polymer precursors preformed by CMRP. This book chapter aims to describe the general principle and main characteristics of such radical coupling techniques involving dienes, nitrones, fullerenes or carbon nanotubes. Well-defined and complex architectures obtained by these techniques are provided in order to illustrate their potential for macromolecular engineering. [less ▲]

Depuis 1830, la Belgique a connu de nombreuses évolutions en matière électorale. Le XIXe siècle et le début du XXe sont notamment marqués par l’ouverture progressive de la participation de la population aux opérations électorales et par leur rationalisation. Au cours des dernières décennies, le système électoral de la Belgique a laissé place à de multiples systèmes électoraux, dans le sillage de la fédéralisation du pays et de la construction européenne. Ainsi, à côté des organes provinciaux et communaux, on ne dénombre pas moins de sept assemblées dont les membres sont directement élus. Même si un certain nombre de règles sont communes à ces différentes institutions, il convient de considérer l’existence d’autant de systèmes électoraux distincts. À ce jour, aucune étude interdisciplinaire n’a fait systématiquement le point sur les systèmes électoraux de la Belgique. Cet ouvrage ambitionne de combler ce vide en réunissant de nombreux spécialistes du droit et de la science politique, mais également de la sociologie, de l’histoire et de la géographie. Une trentaine d’auteurs livrent leurs réflexions sur un thème qui gît au coeur de la vie démocratique d’un pays en pleine mutation. [less ▲]

En raison de leur caractère violent et/ou de leur illégalité, certaines luttes ouvrières font l’objet d’un traitement médiatique et politique stéréotypé les maintenant à un niveau que l’on pourrait qualifier d’infrapolitique (« colère », « coup de sang », etc.). Un terme qualifie, très précisément, jusqu'à l'inflation rhétorique ces actions : « radicalité ». Ce dossier analyse les usages de la notion par divers acteurs (journalistes, juristes, politiques…), les liens entre radicalisation des registres d’action et luttes sociales, ainsi que les déterminants politiques, idéologiques et socio-culturels des discours fixant la frontière entre ce qui, dans une société donnée, relève de l'acceptable et de l'inacceptable.

Offert au Professeur Francis Balace, titulaire de la chaire d’histoire contemporaine à l’Université de Liège, à l’occasion de sa retraite, ce volume rassemble la bibliographie scientifique de l’historien et réunit vingt-trois contributions d’auteurs belges et français qui témoignent à la fois de leurs propres méthodes et champs de recherche et des sujets de prédilection du destinataire. Les textes s’articulent autour de trois grands thèmes. Le premier volet envisage les concepts de radicalité(s) et d’identité(s) tout en s’interrogeant sur les exigences du métier d’historien. Quant aux deuxième et troisième volets, ils explorent la notion de patrie(s) sous deux angles particuliers : les guerres et l’histoire militaire, d’une part, et, de l’autre, les questions diplomatiques et dynastiques.
