Dynamique de fragmentation induite par collision de petits agrégats métalliques

Autor: PICARD, Yan

L'objet de ce travail est l'analyse complète de la fragmentation d'agrégats d'alcalins (Na_n^+ (n < 10), NaK^+ et K_2^+) consécutive à une collision avec une cible légère atomique (He) ou moléculaire (H_2). Il s'agit d'étudier les mécanismes

We present a study of two di fferent sets of Micro-Channel Plates used for time and space resolved single particle detection. We investigate the eff ects of the gold coating and that of introducing an interplate voltage between the spatially separate

In this Letter, we report a demonstration of ion and electron ghost imaging. Two beams of correlated ions and electrons are produced by a photoionization process and accelerated into opposite directions. Using a single time and position sensitive det
