Extended Data Fig. 4 | LLCP in sulfur. a, b, X-ray absorption profiles I/I 0 in the
horizontal (a) and vertical (b) directions in the vicinity of the critical point.
During the measurements, the X-ray beam was stopped by the upper and lower
anvils of the Paris–Edinburgh press. c, d, Horizontal X-ray absorption profiles
at temperatures below (c; 950 K) and above (d; 1,090 K) the critical point. The
red arrow in c indicates the I/I 0 discontinuity at the LLT. No I/I 0 discontinuity is
observed at temperatures above the critical point (d).
