Abstract
EXPERIMENTS have been described1,2 which give data for the fission products of U235 produced in thermal neutron irradiation of natural uranium. Recently, a new radioactive series, not present in Nature, has been reported3,4. Seaborg has shown that U233, a member of this series, is fissile with neutrons. The following is a summary of the results of a survey of the longer-lived fission products of U233. The data were obtained in conjunction with those previously reported1, but could not be released for publication at that time.
