摘要：

The following quantities of shock-compressed liquid krypton are measured behind a plane shock front at pressures up to 90 GPa: compressibility up to densities of 7 g/cm(3), brightness (color) temperatures of 6000-24000 K, and electrical conductivities of 40-60000 (Omega . m)(-1). X-t diagram methods are used to estimate sound speeds of up to 5.5 km/s at pressures of 30-75 GPa. The optical absorption coefficients in the violet and red (30-300 cm(-1)) are measured at pressures of 20-90 GPa from the rise in brightness of the shock front luminosity. The optical reflection coefficient of the shock front (similar to 13%) at a pressure of 76.1 GPa is measured for the first time. (C) 1999 American Institute of Physics. [S1063-7761(99)01408-0].
