(a) Simulated delayed neutron emission profile from 235 and 238U following active interrogation; (b) simulated and measured delayed neutron decay-based discrimination parameter F for 235U and 238U; (c,d) HEU and DU delayed neutron emission profiles measured with the rods-type composite scintillator. Corresponding tabular data fits are overlaid. The only fit parameters are the constant background and neutron emission rate at t = 0
