But that assumption was challenged in an unexpected way by a group of researchers from Purdue University who at the time were more interested in random Numbers than nuclear decay.

但是普渡大学的一组研究者用意想不到的方式挑战了衰变速率恒定这个假设。相比于原子核衰变，他们对随机数更感兴趣。

Only gravity and a phenomenon called the weak nuclear force, which governs some types of radioactive decay, can bind them—hence the term “weakly interacting”.

只有重力和一种可以支配某些放射性衰变的弱核力能够使其聚集凝固，“弱反应”这一术语由此得名。

Quantum tunneling is involved in many physical processes, such as radioactive decay and the nuclear fusion that takes place in the Sun.

量子隧穿发生在许多的物理过程中，比如说放射性衰变和太阳上发生的核聚变。

And the type of nuclear decay each isotope undergoes before it reaches a state.

And this whole topic completely ignores the other, even rarer form of Heliem, the Isotope Helium3, which is formed only as a biproduct of the radioactive decay of the Tritium used in making nuclear missiles.

FORBES: What Great Helium Shortage?

The electroweak force is a synthesis of two previously identified forces of nature, electromagnetism (itself a synthesis, carried out in the 19th century, of the electric and magnetic forces), and the weak nuclear force, which governs radioactive decay.
