Application de la diffusion inélastique aux systèmes désordonnés

Abstract: Résumé. La très grande section efficace incohérente de l'hydrogène, comparée à celle des autres éléments, fait de la diffusion des neutrons une technique privilégiée pour l'analyse des mouvements individuels des protons dans les composés hydrogénés. Nous analysons les origines du déplacement d'un atome diffuseur (vibrations intramoléculaires, modes de réseau, réorientations de groupements chimiques ou rotation d'ensemble des molécules, déplacement de translation). Sous réserve de pouvoir négliger les corrélati… Show more

“…Each instrument gives access to a different time window, determined here to be about 10, 100 and 1000 ps, respectively. Therefore, the instruments can be used as motion filters as the possible movements in biological matter are manifold (translations, rotations or jump diffusion) and correspond to characteristic times, enabling them to be distinguished [28]. The temperature scans were performed within the range of 20-310 K.…”
