Abstract
The gamma-rays associated with the scattering of 14.0 MeV neutrons in extended samples of Possible Fusion reactor materials, Lithium Flouride (LiF) and iron (56 Fe) were investigated. The incident neutrons, were produced by means of the T( d, n) 4 He reaction by using a 150 KeV SAMES Type J accelerator at the university of Aston in Birmingham. The associated-particle time-of-flight technique was used to discriminate between the neutrons and the gamma-rays resulting from the nonelastic scattering processes. For each sample the differential gamma-ray production cross-section in the range of 0–90° were measured with the angular resolution of ±6°. The effect of multiple scattering on the gamma-ray production cross-section as a result of increase in the gamma-ray yield due to an effective increase in the neutron flux was noticed.
