The structure of liquid Sb under pressure

Synchrotron x-ray diffraction measurements of liquid Sb under pressure have revealed that the structure in the low pressure range is not simple-cubic-like nor slightly Peierls-type distorted one, although the coordination number and the pair correlation function show some similarities to that of simple-cubic-like liquid. Structural changes were observed at around 3GPa and 6.5-9GPa. The changes of the peak positions and the coordination number are reported.
