Figure 7. Comparison of x-ray diffraction (XRD) patterns.

Figure 7

(a) The XRD patterns at 123 GPa are simulated for R3m H3S, P1 H5S2, P-1 H2S, Pnma H4S3, and β-Po S with the wavelength λ of 0.41397Å. The experimental data is taken from Fig. 2a of ref. 18, which is obtained by decompression at room temperature after the high-Tc phase is observed at 150 GPa. (b) The XRD patterns at 121 GPa are simulated with λ of 0.6199Å. The experimental data is taken from Fig. 3(a) of ref. 14, which is obtained by compression from 10 GPa at room temperature.
