Popis:	We demonstrate an improved technique for determining the multiplication of highly subcritical systems that uses the moments of the counting distribution from a neutron detector. In the investigation, the multiplications of each of 2, 3, and 4 kg parts of a plutonium sphere were measured and compared with values calculated using three-dimensional Monte Carlo techniques. The measured and calculated neutron multiplications agree within the statistical uncertainties of the measurements and calculations.
