For all we know electrons and quarks are elementary particles, which means that in no experiment has there anything like a structure of these particles been seen. They appear point-like, unlike the proton, neutron, nucleus and atom that have sizes that can be measured. It is, of course, entirely possible that particles that are called elementary today shall turn out to be composite; let it be said though that they have been probed quite extensively.... The aim is to know all about them, their properties and their interactions. The idea is that from this nuclear physics, atomic physics, chemistry, in fact, the whole physical world derives. Thus particles and their interactions are the very fundamentals of nature. That is the view now. An elementary particle physicist studies primarily these elementary particles and not the larger structures such as protons, nuclei or atoms.  1, fiche 1, Anglais, - elementary%20particle%20physicist

In nuclear physics, an atomic nucleus is called a halo nucleus or is said to have a nuclear halo when it has a core nucleus surrounded by a halo of orbiting protons or neutrons. The electrons then orbit the core nucleus much further away than the orbit of the halo nucleons.  2, fiche 2, Anglais, - halo%20nucleus

Les noyaux les plus légers possèdent des propriétés étonnantes, c'est le cas des noyaux à halos comme le Lithium 11 ou le Béryllium 14. Ces noyaux comportent un halo formé d'un ou plusieurs neutrons, qui se trouvent à une distance importante du reste du noyau.  2, fiche 2, Français, - noyau%20%C3%A0%20halo

La physique du noyau. Niché au cœur de l'atome, le noyau n'a pas encore dévoilé tous ses secrets. En effet, il est composé d'un ensemble de n (1 à 300) nucléons (neutrons et protons) et sa compréhension nécessiterait à la fois de bien connaître les forces de cohésion mises en jeu, et de résoudre mathématiquement le problème de n corps en interaction. Aucun des ces deux problèmes n'est à l'heure actuelle complètement résolu.  2, fiche 4, Français, - physique%20du%20noyau

Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around the nucleus and the processes by which these arrangements change.  2, fiche 5, Anglais, - atomic%20physics

The term atomic physics is often associated with nuclear power and nuclear bombs, due to the synonymous use of atomic and nuclear in standard English. However, physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone.  2, fiche 5, Anglais, - atomic%20physics

La physique atomique est le champ de la physique qui étudie les atomes en tant que systèmes isolés qui comprennent les électrons et le noyau atomique. Elle se concentre essentiellement sur l'arrangement des électrons autour du noyau et sur la façon dont celui-ci est modifié. Cette définition englobe tant les ions que les atomes électriquement neutres.  2, fiche 5, Français, - physique%20atomique
