Cet article présente de la structure de plusieurs noyaux atomiques en utilisant l'approximation de la dynamique moléculaire antisymétrisée (AMD). Après un bref rappel mettant en avant la possibilité de faire des calculs ab initio, nous montrons que cette approche permet de comprendre différents problèmes de structure nucléaire bien connus pour les noyaux stables. En particulier, elle donne une description unifiée des comportements de type champ moyen et de l'apparition d'agrégats de nucléons. Pour finir, nous appliquons AMD aux noyaux instables (exotiques) et nous illustrons qu'une telle approche fournit une explication et une compréhension des différentes structures découvertes avec les noyaux exotiques.

The AMD theory for nuclear structure is explained by showing its actual applications. First the formulation of AMD including various refined versions is briefly presented and its characteristics are discussed, putting a stress on its nature as an ab initio theory. Then we demonstrate fruitful applications to various structure problems in stable nuclei, in order to explicitly verify the ab initio nature of AMD, especially the ability to describe both mean-field-type structure and cluster structure. Finally, we show the results of applications of AMD to unstable nuclei, from which we see that AMD is powerful in elucidating and understanding various types of nuclear structure of unstable nuclei.
