摘要：

The model developed for describing the response of neutron-coincidence setups taking into account the real leakage-neutron multiplicity distribution (RMD approximation) is effective for analyzing samples of metallic plutonium with different isotopic composition, plutonium dioxide, and composites of mixed uranium - plutonium fuel in the form of powder and granules. The only inconvenience of this model, just as the BEH approximation, is that computational or experimental estimates of the multiplication effect must be obtained. The quantities Km, Ss*, and Sin* can be calculated on personal computers. For IBM-PS/2 computers one calculation requires 5 min. In the future we intend to extend the approach developed in this paper to setups employing analysis of multiple neutron coincidences (triple, and so on). Then there is evidently no need to estimate the multiplication effect in advance. © 1994 Plenum Publishing Corporation.
