Descripción
In this article we present a model that describes the total cross-section of molecular liquids, aiming to provide a good description in the subthermal energy range with a minimum number of parameters, amenable to perform calculations of interest in Nuclear Engineering. We follow the spirit of Granada´s Synthetic model that was successful in the thermal and epithermal ranges. The model describes the incoherent cross-section and is suited for hydrogenated liquids. We apply the model to light water at room temperature. The results compare favorably with experimental data. We compare with other models that describe the subthermal cross-sections. In the description we stress the need to have a good knowledge of the vibrational intermolecular energy spectrum, and the diffusion constant.
