The kingfisher is generally considered as strongly territorial. However, different pairs are sometimes nesting at very close quarters. Two male kingfishers nesting along the river Meuse (Belgium) at a distance of less than 500 m were radiotagged. Their respective home range (5.2 and 7.2 km) were largely overlapping, some fishing grounds being used simultaneously by both birds. Some kind of territorial defence (a bird chasing its neighbour) has been observed in a very limitid area around the nesting places. [less ▲]

The appearance of negative ions by dissociative electron attachment has been studied by electron impact on CH4, C2H2, C2H4 and C2H3X (X=F, Cl) using a sector field mass spectrometer. An interpretation has been attempted for the measured appearance potentials. The electronaffinity of C2 and C2H is found to be (3.3+/-0.3) eV and (2.3+/-0.2) eV respectively. Some evidence is brought for the existence of excited electronic states in polyatomic negative ions. [less ▲]

The negative fragment ions appearing in methane have been investigated using a sector field mass spectrometer. By recording the ionzation efficiency curves of each ion it has been possible to determine the appearance potentials for several processes. Interpretations of the mechanisms for these critical potentials have been attempted. [less ▲]

The study by mass spectrometry with electrospray ionization of organometallic complexes was performed in order to elucidate the mechanism of reduction of ions in the gas phase that occurs in the region of the cone of the electrospray source. The prospects of this work are a better understanding of the mechanisms of fragmentation of ions in the gas phase in the area of the source and the opportunity to study the reactions of these complexes in the absence of solvent.

La spectroscopie vibrationnelle non-linéaire par génération de la fréquence somme est une sonde particulièrement adaptée à l'étude des interfaces entre milieux denses. Cette technique a été appliquée à l'étude de l'interface électrochimique monocristal de platine/solution acide de méthanol, système qui constitue un modèle de pile à combustible, dispositif où l'énergie chimique est directement convertie en énergie électrique. Les propriétés vibrationnelles dépendent fortement de l'orientation cristallographique de l'électrode de platine. [less ▲]
