Roeland, L W

Bohr's unified model of the nucleus was tested by an investigation of the mass distribution of fragments resulting from fissions induced by neutrons at one particular resonance. After a general introduction to the experimental set- up, A. Bohr's theory is outlined. The construction and properties with respect to fission fragment pulses of gridded ionization chambers are then discussed. The electrical equipment the neutron filter technique, and some details on the actual performance of the equipment are reviewed. Measurements on U/sup 235/ and U/sup 233/ are then given and discussed. The conclusion is that the dependence of the mass distribution on the spin of the fissioning nucleus, as predicted by A. Bohr, may be proved by an experiment which compares fission by epithermal and thermal neutrons. (J.S.R.)
