✦ Synopsis

A pneumatic transfer system used in delayed neutron experiments is described. The system enabled small samples of fissionable materials to be irradiated near the reactor core for preset times of & set or longer and transferred in less than one second to a remote neutron detector. The yields of five groups of delayed neutrons resulting from fast fission of Ue3&, Uzss, Uz38, Puz3$, and Thea* were investigated and compared with previous results. Some evidence was found that a shortlived precursor contributes to a small extent to the observed twenty-two-second group.
