Abstract/Summary:
An experimental method has been developed for making time resolved reflection measurements on shock compressed liquid CS;In multiple shock experiments the reflectance increases continuously with pressure and, inside spectral regions of absorption, is found to change at times coincident with shock wave arrival at the rear CS;A reflection experiment on a thin (;Double shock experiments at peak pressures up to 89 Kbar showed no evidence of chemical reactions. At peak pressures of 96 and 99 Kbar the reflectance at wavelengths less than 400 nm decrease with time. The nature of this decrease was in agreement with the pressure history, at the rear CS;Analysis using the Fresnel reflection equations and a complex refractive index for CS...
