光电子的英文：
phoelectron
photoelectron
photoelectrons

In these circumstances one finds that photoelectrons appear as soon as the light is switched on
实际上，人们总是发现，只要光一照射，光电子就立即发出。

Let us work out the time that would be taken for an atom to absorb the energy required to produce a photoelectron
让我们求出一个原子产生一个光电子吸收所需能量应该经历的时间。

excitation radiation may do this by penetrating to the cathode and ejecting a photoelectron
激发辐射可能射到阴极，逐出一个光电子，从而引起这个。
