Description
The exceptional properties of liquid helium make it a favorable medium for ultra-cold neutron production at neutron scattering facilities. In previous work, we presented a model for Monte Carlo simulations of neutron scattering in superfluid helium at temperatures up to approximately 1.3 K [1]. However, a complete description of neutron interactions in the material also requires a model for the normal phase at higher temperatures. Here we describe progress toward completing this description.
