Fig. 1From: The sound velocity of wüstite at high pressures: implications for low-velocity anomalies at the base of the lower mantleAn example of IXS spectra at 59.4 GPa and 1700 K. The spectra include individual contributions (elastic scattering, the longitudinal acoustic (LA) mode of tungsten, the LA mode of B1-FeO, and the transverse acoustic (TA) mode of the diamond anvil) fitting the experimental data with Lorentzian functionsBack to article page
