The pressure just after the compression was higher than the equilibrium pressure but lower than the Pade approximant pressure, from which we conclude that the shortcoming of the truncatedvirial expansion is not due to h freezing phenomena (or to the appearance of a hexatic phase ' ). However,it means that the first-order nature is less pronounced than found in Ref. 13, and it implies that the tie line appears at a higher pressure.The calculated tie line (dotted line) appears at
