“Data for this entry were determined on some or all of the following shots: 8A-238, -302, -305, -306,
and -318; each was fired using several plate thicknesses.

Analysis
Linear least squares fitting gives Uf, = 3.531 km/s - 0.01029 t (mm). At t = 0,
plate U, = ‘7.704 km/s and P, = 37.57 GPa. Acoustic approximation of D = 8.252
km/s, pox =, 1.743 g/cm3, and ,oom = 2.793 g/cm3 gives corresponding explosive
parameters of P, = 31.34 GPa, U,, = 2.179 km/s, and y = 2.787.
