As we all things quantum mechanical it is a matter of probabilities. In fact there is a probability a neutron can pass right through a nucleus and leave the mass number unchanged. The probability that a neutron will be absorbed by a nucleus is proportional to the speed of the neutron. After it is absorbed the nucleus can undergo fission or whatever. Harry
