AbstractAbstract
[en] The multiple coincidence technique uses 14.1 MeV neutrons to produce (n, multiple-γ) coincidences to detect fissile and fissionable materials. Measurements of n-γ-γ coincidences with targets of depleted uranium (DU), W, and Pb, show that the counting rate for the DU is substantially above that for the non-fissionables. Also, the data involving prompt neutrons and delayed gammas in the DU time spectra provide a signature for fissionables that is distinct from that of non-fissionables
