X-ray scattering techniques are a family of nondestructive analytical techniques. Using these techniques, scientists obtain information about the crystal structure and chemical and physical properties of materials. Nowadays, different techniques are based on observing the scattered intensity of an X...

. — L'introduction de corrections relativistes aux effets électromagnétiques intervenant dans le traitement de la diffusion élastique proton-proton aux basses énergies est affectée d'un certain nombre d'ambiguïtés fondamentales. La portée de ces dernières est examinée au niveau de l'analyse des donn...
Les principes de l'utilisation des faisceaux d'ions légers monocinétiques d'une énergie de l'ordre du MeV, à l'analyse d'impuretés dans, ou sur, des substrats solides sont exposés. Deux techniques complémentaires sont décrites : a) l'utilisation de la diffusion élastique qui permet d'analyser des él...
The elastic scattering differential cross section of ɑ-particles by ɑ-nuclei described in the ɑ-model has been calculated in the plane-wave Born approximation. It is shown that, when the target nucleus is Be8 and the range of the interaction between ɑ-particles is zero, the contribution of the heavy...
The quasi-nuclear phase shifts obtained from elastic scattering expriments with charged particles are corrected in order to derive true nuclear phase shifts (i. e. phase shifts corresponding to fictituous neutral particles with the same strong interaction properties). At a given energy, the correcti...
