Figure 6
Integrated X-ray diffraction profiles collected at increasing time (from bottom to top) showing release of b.c.t.-Sn from the first observation at high pressure (10.0 GPa) to the lowest pressure observed (7.1 GPa). Each profile represents a separate data collection on a new area of the sample. After a period of time, the pressure in the compressed region of the sample was lower than 7.1 GPa and b.c.t.-Sn was not observed, which is in good agreement with the existing b.c.t.-Sn to β-Sn transition from shock studies. |
