中子衰变

列举了中子衰变弱相互作用常数和中子电偶极矩的最近测量结果。

The newest experimental results of weak interaction constants defined in neutron decay and neutron electrical dipole moment are given .

在零功率堆中子衰变常数（α常数）瞬态测量实验时，必须进行本底中子的屏蔽。

It is necessary to shield the background neutron during the measurements of neutron decay constant on the zero power assembly .

让我们首先来计算一个自由中子的衰变会释放出多少能量。

Let us calculate first how much energy is released when a free neutron decays .

由于铀，钍、锕三系能直接发射微量重离子~（14）C，以及自发裂变中子和α-衰变与物质发生核相互作用，也可产生~（14）C。

Heavy-ion 14 ~ C can not only be directly emitted by three radioactive series ( 238 ~ U , 235 ~ U and 232 ~ Th ), but can also be produced by neutrons of the spontaneous fission and α - decay interacting with matter .

被捕捉的中子在贝它衰变时可被侦测到，因为在超流体中带有能量的衰变电子可游离氦原子导致电子动能有效地转换成光子（闪烁）。

Trapped neutrons are detected when they beta decay ; energetic decay electrons ionize helium atoms in the superfluid resulting in efficient conversion of electron kinetic energy into light ( scintillation ) .
