Abstract : We show that the acoustic branches calculated by our helical lattice dynamics calculations can match the observed inelastic neutron scattering results. The fit in the neutron sub Terrahertz region is consistent with our fit to Brillouin results in the Gegahertz region when the frequency dependence of the dielectric constant of water is taken into account.
