A Study of the Elastic Scattering of 2 to 3 MeV Neutrons by 40Ca and 32S Using an Associated Particle Time of Flight Spectrometer
An associated particle time of flight spectrometer based on the D(d,n)3He reaction has been developed using thin deuterated polythene targets. The competing D(d,p)3T was used to monitor the neutron output. The spectrometer has been used to study the elastic scattering of a 2 - 3 MeV neutrons in 40Ca and 32S; in each case the differential elastic scattering cross sections have been measured. In the angular range 20° - 100° in the laboratory frame of reference the results have been compared with an optical model analysis. Values of ¿2 per point of 3.46 and 2.84 for 40C and 32S respectively were obtained.
The elastic scattering of 14 MeV neutrons in large samples of iron.
Abstract The differential cross-sections for the elastic scattering of 14 MeV neutrons from iron have been measured for various sample thicknesses using an associated particle time of flight spectrometer. The variation of the cross-sections with sample thickness has been measured and the results for the smallest sample compared to the predictions of the optical model.
