New method for the measurement of differential elastic scattering cross sections of fast neutrons

A new method has been described which successfully reduces the problem of low scattering intensity. The scatterer has been taken in the form of a spheroid. The elastically scattered neutrons have been discriminated from the inelastically scattered ones by using multiple bias technique. Experimentally measured values of differential elastic scattering cross sections for sulfur at four angles for 14 MeV neutrons have been presented. The results have also been compared with the optical model prediction
