Total and differential fission cross sections of uranium and thorium for low energy deuterons

A method of recording fission fragments with glasses is used for determining the total and differentiae fission cross sections of Th²³², U²³³, U²³⁵, and U²³⁸ for deuterons with energy considerably below the Coulomb barrier –6.6 MeV and less. The results are compared with data from published papers in which the same quantities were studied by means of semiconductor detectors in the region of high-energy deuterons. New facts are noted, which indicate that for nuclei with different neutron fission thresholds, as a result of irradition with sub-barrier deuterons, the reactions preceding fission may differ considerably.Translated from Atomnaya Énergiya, Vol. 18, No. 5, pp. 456–459, May, 1965
