They would form helium and a subatomic particle, called a neutron.
聚變後形成氦以及一種稱爲(wèi)“中子”的亞原子粒子。
But the lead ion collisions will be different; because lead ions are composed of complete atomic nuclei – not just a single subatomic particle – their masses are far larger.
但是鉛離子的對撞將會是不同的；因爲(wèi)鉛離子完全由原子核組成——而不僅僅衹是一個單一的亞原子粒子（subatomic particle）——它們的質(zhì)量要大得多。
They typically take place when a nucleus of an atom gets smacked by either a subatomic particle (usually a "free neutron, " a short-lived neutron not bound to an existing nucleus) or another nucleus.
儅原子的原子核被亞原子微粒（通常是“自由中子”，一種原子核所束縛的短命中子）或另一個原子核碰撞時，核反應(yīng)就會爆發(fā)。

The energy released in fusion is carried mostly by neutrons, a type of subatomic particle that has no electric charge and hence cannot be confined by the magnetic bottle.

Dr Kobayashi and Dr Maskawa, who were at Japan's High Energy Accelerator Research Organisation and Kyoto University respectively, described a type of symmetry breaking that predicted two new families of quarks, a sort of subatomic particle whose simplest members are the ingredients of the protons and neutrons that form atomic nuclei.
