    • In Ref. 7, which found a large resonance, Reitze et al. showed that after a femtosecond laser pulse the liquid reflectivity is very high, and decays rapidly within a few picoseconds. This could indicate the formation of a "metallic" liquid during the very short time interval in which, the liquid, not yet being expanded, is submitted to large inner compressive stresses. After expansion, the measured reflectivity falls down to levels typical for nonconducting materials. However, pressures and temperatures are, in this experiment, not measurable.

    • We believe that the lower thermal conductivity of RW1, compared to that of HOPG graphite in the crystallographic base plane (corresponding to the heated surface), creates thermal conditions which depress liquid displacement.

    • In the previous experiments HOPG was mainly used; we could recognize only later that this type of graphite provides poorer liquid stability conditions.

    • 3/mole), one obtains 21.2 cal/K, which is very near to the value predicted by Trouton's rule. This should indicate that liquid graphite has a structure whose "free volume" is not very different from that of most of the other liquids.

    • note
    • This equation of state, based on the scaling theory, contains a Lindemann-type model for a mixture of liquid graphite and liquid diamond. The maximum of the melting line is calculated at approximately 50 kbar/4950 K by assuming the SLV triple point of graphite at 4550 K.
