Abstract: The prompt fission neutron spectrum (PFNS) was measured at 0.5 MeV incident neutron energy. An angular anisotropy in the prompt neutron emission was found. The neutron yield is ~10% higher and the average energy ~80 keV smaller at 90 degree than at 120 degree neutron emission angle. The spectral difference diminishes with increasing prompt neutron energy. The experimental data were successfully described with the semi-empirical "three sources" model.
