Abstract: | 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/cm3, brightness (color) temperatures of 6000–24000 K, and electrical conductivities of 40–60000 (Ω·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 (∼13%) at a pressure of 76.1 GPa is measured for the first time.
