Measurements have been made of the angular distribution of fission fragments from ²³⁵U at three fast-neutron energies. Results are fit by the expression W(θ) = 1 + A₂cos²θ, with the anisotropy factor, A₂, found to be −0.010 ± 0.014 at 265 keV, +0.137 ± 0.016 at 770 keV, and +0.157 ± 0.019 at 964 keV.
