Fission-fragment angular distributions and total kinetic energies for /sup 235/U(n,f) from. 18 to 8. 83 MeV
A gridded ion chamber was used to measure the fission fragment angular distribution and total kinetic energy for the /sup 235/U(n,f) reaction from 0.18 to 8.81 MeV neutron energy. The anisotropies are in generally good agreement with earlier measurements. The average total kinetic energy is approx. 0.2 MeV greater than the thermal value at neutron energies < 2 MeV and shows a sudden decrease of approx. 0.8 MeV between 4 and 5 MeV neutron energy, well below the (n, n'f) threshold. Possible causes of this decrease are a change in the mass distribution or decreased shell effects in the heavy fragment.
