“…Neutron multiplicity counting is an established method to estimate the spontaneous fission rate, and therefore the Plutonium mass for example, in a sample that includes other neutron sources [1][2][3]. The probability distribution describing the number of neutrons detected in a short time window (256 ms for example) is typically summarized by its first few moments.…”

“…[8,1,12] Factorial moments in this report are represented by the character with a primary subscript of 's' or 'i' denoting whether it is a moment of the multiplicity distribution of the spontaneous fission of 240 Pu or the induced fission of 239 Pu respectively. For all calculations described in this report the multiplicity distribution for fission induced by a 2 MeV neutron was used to determine all i factorial moments.…”

“…Empirically, this rate can be calculated as: ), İ = detection efficiency, M = sample multiplication (leakage), and Į = the ratio of (D,n) neutrons to spontaneous fission neutrons. [5,8,9] * For this report, factorial moments with subscript "s" denote spontaneous fission, while those without this marking correspond to induced fission. The detected neutron doubles rate, D, is dependent on spontaneous fission, induced fission, and (Į,n) reactions.…”
