When you split a uranium 235 atom you will create what we call fission fragments.
当你们将铀235原子分离的时候,你会创造出我们称为裂变碎片的。

We can then look at uranium 238 which has a relatively low absorption thermal energy range and essentially has no fission cross section which is why we call uranium 238 a fertile atom.
A neutron striking a uranium 235 atom, releasing some gammas and some neutrons, creating two fission fragments which themselves have a distribution of occurrence.
