A clear set of well-defined peaks equally separated in energy is observed in UC, corresponding to harmonic oscillations of the light C atoms in a cage of heavy U atoms. The scattering is much weaker in US and only a few oscillator peaks are visible. We show how the difference between the materials can be understood by considering the neutron scattering lengths and masses of the lighter atoms. Monte Carlo ray tracing is used to simulate the scattering, with near quan","authors_text":"A.A. Aczel, D.L. Abernathy, G.D. Samolyuk, G.E. Granroth, G.M. Stocks, J.Y.Y. Lin, M.B. Stone, S.E.
