Monte Carlo analysis of the Oak Ridge National Laboratory measurements of the fission neutron yield due to the absorption of a 2200 m/sec neutron in 233U and 235U, respectively, yields: = 2.3019 ± 0.0086 and = 2.0746 ± 0.0078. The analysis was confirmed by calculating measured quantities employed by the experimentalists in their determinations of η2200.
