A new way of utilizing the fast Fourier transform is developed to compute the probability distribution for a fission chain to create n neutrons. We then extend this technique to compute the probability distributions for detecting n neutrons. Our technique can be used for fission chains initiated by either a single neutron inducing a fission or by the spontaneous fission of another isotope.
