Figure 8
In situ high-P–T nuclear resonance inelastic scattering (NRIXS) measurements of ∊-Fe. Top: spectra at 300 K and 1500 K at 50.5 and 54.7 GPa, respectively. Bottom: comparison of the temperature obtained from the thermal radiation (assuming a grey-body) and that obtained from the temperature dependence of the spectrum using detailed balance (Lin, Sturhahn et al., 2004). |
