Measured emissivities of uranium and tungsten plasmas.Uranium and tungsten absorption coefficients between 2,500-8500 A were measured as functions of thermodynamic variables. A gas-driven shock tube was used to obtain plasma temperatures, heavy metal partial pressures, and total pressures in the ranges 7,000-12,000 K, 0.02-1.0 atm, and 3.0-48 atm, respectively. Emission and absorption data were recorded both photographically and photoelectrically. The spectral distributions, thermal dependence and line-to-continuum ratios of the uranium and tungsten radiation differ distinctly. The uranium data are compared with theoretical predictions and with results from other experiments.
