The one-dimensional shock waves, which were used to compress the medium, were produced by impacting an aluminum target with a flat-nosed projectile. The elastic shock wave velocity was measured as 6.23±0.15 mm/[mu]. Above the Hugoniot elastic limit of 6.3±0.1 kilobars both elastic and plastic shocks were observed. The particle velocity behind the shock front, determined at the plane of impact, was compared to the free surface velocity. Above the elastic limit the free surface velocity was less than twice the initial particle velocity and appeared to be a function of the thickness of the target.
