THERMAL-NEUTRON CROSS-SECTIONS AND DIFFUSION PARAMETERS OF DIPHENYL AND DOWTHERM-A USING A SYNTHETIC SCATTERING FUNCTION

We have used a synthetic scattering function to evaluate thermal neutron cross sections and diffusion parameters for diphenyl and Dowtherm-A, over a range of temperatures of practical interest. The present formalism is based on our benzene model, which has been already validated in a previous application. Our calculated results for diphenyl are in excellent agreement with several measured quantities, whereas those for Dowtherm-A are at variance with the scarce available information.
