Unlike most other elements lighter than iron, the light nuclei of lithium, beryllium and boron are not produced in significant amounts in stars.

不同于大多数比铁轻的元素，Li、Be、B等轻元素大部分不是在恒星内制造的。

In addition, the decay from WIMP to super-WIMP should have produced photons or electrons as a by-product, and these particles can smash into light nuclei and break them apart.

而且，在弱相互作用重粒子衰变成超级弱相互作用重粒子过程中，应该产生光子和电子等副产品，并且这些粒子也会与质量较轻的原子核发生碰撞，将它们撞碎。

Because protons and neutrons in light nuclei fill the same shell, it is necessary to introduce isospin when the light nuclei are described by the interacting boson model (IBM).

由于在轻核中质子与中子处于同一壳，当用相互作用玻色子模型(ibm)描述轻核时，必须引入同位旋。

It was generated at the Relativistic Heavy Ion Collider (RHIC) in New York, US, which smashes beams of gold nuclei together at near light speeds.

Neutrons ejected from a watery surface move much more slowly than those from a rocky one, because the hydrogen nuclei in water are light enough for an exiting neutron to knock around much like one billiard ball hitting another a process that slows the neutron down.

But in Dr Rostoker's reactor, the helium nuclei created by the process of light fission would be speedy enough to escape from the ends of the ellipsoid, where the magnetic field is weakest.
