Quasi-isentropic compression of liquid argon at pressure ≈ 1000 GPa

The measurement of the density of liquid argon at a pressure of about 1000 GPa in a cylindrical setup transforming shock compression to quasi-isentropic compression gives a value of about 9 g/cm³. The experimental data are compared with calculations. The results bring out clearly that no anomaly is observed in the behavior of isentropically compressed liquid argon at pressures up to about 1000 GPa.
