Introduction
Every individual photon pulse may cause any number of neutron-producing reactions, hereafter denoted by , ranging form zero to "infinity". , being the number of neutron-producing reactions actually occurring per pulse, is assumed to follow the Poissonian distribution as a limiting case of the binomial distribution. Each neutron-producing interaction produces neutrons, where is the distribution of the number of neutrons produced from a single given neutron-producing reaction. Since only two neutron-producing interactions are energetically possible in this experiment, is simply the photo-fission neutron multiplicity plus a contribution from 1n-knockout events. In other words, 1n-knockout is considered an event with neutron multiplicity of one, and equivalently for a photo-fission event with a multiplicity of one.
