PDFs and excess diffuse scattering functions obtained at 636 mJ cm−2 pump laser fluence as a function of pump–probe delay time. (a) Waterfall plot where the peak broadening can be identified as a function of time delay. (b) Detailed plots at three representative time delays, together with a PDF calculated from the measured F(Q) at 1423 K (Waseda & Ohtani, 1974BB18). (c) Excess diffuse scattering profile extracted by removal of the Bragg peak contributions and subtraction of the profile measured at negative time delay. The measured structure factor of liquid gold is shown at two temperatures in colour at the top of the panel. (d) Results of Gaussian fitting of the first maximum of the structure factor as a function of pump–probe delay time.
