原子核

In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

扎采品表示，充有高能量的粒子（大多数太空射线都属于原子核，因此也就具有正电）应该会由于太空微波背景下（渗透到整个宇宙的大碰撞所遗留下的辐射）的光子碰撞而减慢速度。

In the event of neutron capture, the mass number of the nucleus will be raised, and it will thus become unstable and radioactive.

一旦俘获了中子，原子核的质量数便会增加，因而也就会变得不稳定并且具有放射性。

However, with mass-energy relation formula, the loss of helium-4 nucleus quality, equivalent to happen because of the reaction of atomic energy and reduce the release of the quality!

然而，用质能关系公式计算，氦4原子核失去的质量，恰巧等于因反应时释放出原子能而减少的质量！
