beta decay

The radioactive transformation giving rise to these electrons was known as beta decay.

产生这种电子的放射性变化,称为β衰变.

Double beta decay in nuclei plays an important role in testing lepton number conservation and neutrino mass.

原子核双β衰变在检验轻子数守恒律和中微子质量等问题上都起了重要的作用。

Let us very briefly rehearse one or two facts about nuclear beta decay.

让我们非常简要地复述一下有关该β衰变的一两件事实.

Radioactive series: Any of four sets of unstable heavy atomic nuclei that undergo a series of alpha decay and Beta decay until a stable nucleus is achieved.

放射性系：四组不稳定的重原子核，通过一系列α衰变和β衰变直至达到稳定的核为止。

A method is described for measuring the beta spectrum from tritium decay in order to determine the electron-antineutrino rest mass.
