REPLY TO COMMENT ON 'DEPOLARIZED LIGHT SCATTERING STUDY OF MOLTEN ZINC CHLORIDE'

Our reply to Ngai and Roland's comment emphasizes that our analysis of the Zn${\mathrm{Cl}}_{2}$ depolarized light scattering spectrum was only designed for proving the existence of a boson peak and revealing its thermal evolution. This analysis, as well as Ngai and Roland's one, are based on a separation between relaxational and vibrational contributions, which has up to now no theoretical justification.
