WebJun 1, 2024 · The fission process occurs because incident neutrons are “absorbed” in a fissile nucleus, and an excited state is produced. This excited state makes the nucleus very unstable, and if the compounded nucleus is excited enough, a fission of the nucleus occurs (or splitting). When this fission occurs, new product nuclei (such as Sr-90 or Cs-137 ...
