OPACITY OF HOT, HIGHLY COMPRESSED HYDROGEN.
Abstract
The rapid gas compression technique employing a ballistic piston compressor was adapted to the study of the opacity of hydrogen at elevated pressures and temperatures. Hydrogen/helium mixtures were compressed for short times to pressures and temperatures exceeding 2500 atmospheres and 5000K, and the emission spectra were recorded and analyzed. The discrete line spectra were identified as due to metallic impurities, but the strong background continua could not be ascribed unequivocally to hydrogen. Computer calculations of the specie concentrations that comprise hot, highly compressed hydrogen/helium mixtures were made, and possible opacity producing mechanisms were advanced to explain the observed continua.
