Abstract

The unreported heavy neutron-rich nuclide237Th has been identified for the first time. Sources of237Th prepared by 14-MeV neutron irradiation of uranium followed by radiochemical separation have been studied. The new activity of237Th was identified by following the time variation of the characteristic γ-rays. The half-life of237Th has been determined to be 5.0±0.9 min.
