Quasi-infinite medium neutron spectra have been measured as a function of moderator temperature and poison concentrations in water. Three different poisons were used: a l/υ absorber (boron), and the resonance absorbers erbium and gadolinium. These measurements were performed utilizing the General Atomic Linac and standard time-of-flight techniques. The temperature range covered was from ambient to about 300°C. The measurements were compared to the latest theoretical models using the best known calculational techniques available. The scattering kernel based on the modified Haywood frequency spectra and computed by the GASKET-FLANGE computer codes appears to give the best agreement with the experimental data.
