“…In general one may conclude that the present experiment at 90 degree together with nearly all other available numerical data does not confirm the Madland-Nix model [1] or its latest modifications [3]. At presence no model can explain the experimental finding of an anisotropic PFN emission.…”

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.

“…It was based on the well known assumption that all fission neutrons are emitted from accelerated fragments. This model or its recent modification [3] has been tested with integral experiments [4] and reasonable well predicts benchmark experiments [5].…”

“…For each FF mass pair, two isobars per fragment mass were taken, with values for the nuclear charge Z chosen as the nearest integer values above and below the most probable charge Z p , according to Ref. [43] and refer- ences therein. Consequently for 237 Np(n, f) 84 FF pairs were used in the PbP calculations.…”
