Abstract
The total kinetic energy (TKE) release in the fast neutron induced fission of 235U was measured for neutron energies En=2-100MeV. The TKE distributions are Gaussian in shape. The mean post neutron emission TKE release decreases non-linearly with increasing neutron energy and can be represented as TKE(MeV)=170.92â3.73774log10â¡Enâ0.65028(log10â¡En)2. Abrupt changes in the variances of the TKE distributions are observed at the onset of 2nd, 3rd, etc. chance fission. For En=20-100MeV, the variances are approximately constant. These observations are compared to the predictions of the GEF model for neutron-induced fission. This model describes many of the features of the TKE release adequately.
