    • In any case care has to be taken in interpreting such broadening because the line shape of the resonances is unknown. For a single phonon it could be assumed a Lorenz function reflecting the finite lifetime of the excitation. However, when taking a powder average the line shape acquires a nonanalytic form even for the crystal due to the anisotropy within the multidimensional dispersion sheet.

    • Cubic ice is not a perfect crystal due to the presence of staking faults [W. F. Kuhs, D. V. Bliss, and J. L. Finney, J. Phys. (Paris), Colloq. 48, Cl-631 (1987)]. This is an interesting subject in its own, however, without incidence on the discussion of the amorphous phases presented here.

    • c is a good reference system for LDA this may not be the case for HDA, HDA has supposedly a bonding topology closer related to high-density ice forms like ice XII, which is formed under similar conditions [12].

    • note
    • Brute force fitting of a damped harmonic oscillator (DHO) - frequently used in previous analysis of IXS data - would lead to overdamping at large Q. The DHO, however, does not make any physical sense in the Q region where the spectra already reflect the specific features of the phonon density of states.
