Prompt and delayed neutrons (DN) from pulsed irradiation of geometrically identical natural uranium and lead targets by 1 and 4 GeV deuterons were measured at NUCLOTRON facility of Joint Institute for Nuclear Research. The massive hexagonal shaped targets were surrounded by 10 cm lead blanket. Neutrons were measured by the assembly of ^3He counters embedded in moderator and by threshold activation detectors. The DN decay curves were analysed for both targets and information on fission properties for massive (∼315 kg) uranium target was extracted. The obtained experimental information could be useful for verification of INC and transport codes. The results of this experiment are important for development of advanced ADS systems and other applications.
