beta decay

1 In double beta decay, the interaction is doubled: Two neutrons simultaneously decay into two protons.

2 Rarely, a proton in the oil will absorb an electron antineutrino to turn into a neutron while ejecting a positron—sort of the reverse of beta decay.

3 Wu was the first scientist to confirm — and later refine — Enrico Fermi’s theory of radioactive beta decay.

4 If this is the case, then when double beta decay occurs, two neutrinos would be produced and immediately annihilated, leaving none behind.

5 Over multiple experiments, Pauli’s contemporaries had noticed an accounting error when observing beta decay, a process by which certain radioactive atoms break down.

6 Fermi’s model of beta decay took a vague suggestion by Wolfgang Pauli and turned it into a rigorous mathematical theory, and his work in statistical physics is critical to modern condensed matter physics.

7 The basic structure of beta decay is a neutron decays into a proton, electron, and neutrino.

8 For instance, to ensure that a neutrino emitted from beta decay would interact in a detector made of, for example, solid lead, the detector would need to be many light years thick.

9 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.

10 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.

11 No connection between simplicity and decay appears.

基本性与衰变之间没有联系。

12 What do we know from Time and Decay?

怎么大家都知道，从时间和衰变的呢？
