Strong Interactions in Nuclear Physics

自然界中的粒子有两种基本形式：费米子(可以说是“孤立的”实体)和玻色子(其中许多粒子可以组合在一起)。费米子构成了物质的所有基本成分，如电子、质子、中子，甚至夸克。因此，可以合理地说，核物理学研究的是费米子。核子(一个用来描述质子或中子的术语)不仅组成原子内部的原子核，而且还独立出现在被称为中子星的密集天体中(即原子核外部)。

Particles in nature come in two fundamental varieties: fermions (which, it may be said, are "solitary" entities) and bosons (many of which can group together). Fermions make up all the basic ingredients of matter, such as electrons, protons, neutrons, and even quarks. Thus, it can be reasonably said that nuclear physics deals with fermions. Nucleons (a term used to describe either protons or neutrons) not only make up the nuclei inside of atoms, but also appear on their own (i.e. outside nuclei) in the dense astrophysical objects known as neutron stars.
