ABSTRACT IN continuation of the experiments on uranium fission under deuteron bombardment reported by Gant1 from this laboratory, we have carried out a chemical separation of the recoil
products. The particles projected from the uranium target under deuteron bombardment were collected on an aluminium foil using the experimental arrangement described by Gant. The foil was
then dissolved in aqua regia and, after adding the necessary carriers, platinum, barium and lanthanum separations were made in the usual way. The activities observed were 15 min., 1 hr. and
30–40 hr. with the platinum fraction, 11 min. and 80 min. with the barium fraction, and 4 hr. with the lanthanum fraction. Some of the periods are thus found to correspond to those obtained
with neutron fission in uranium2, in agreement with Gant's conclusion that 9 Mev. deuterons are capable of producing fission in uranium. Control experiments with lead and bismuth
targets failed to show any appreciable activities in the carriers. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution
