Abstract:

The thermal radiation emitted from rapidly compressed monatomic gases in the NOL Adiabatic Compressor was spectrographically analysed, and shown to be the spectra of vaporized components of the compressor. Experiments to introduce and to excite selected emitters in the compressor were successful, whereas experiments to eliminate the radiation from the vaporized compressor components met with only partial success. Effects due to collisions of the emitting atoms with perturbing atoms were observed in the radiation namely, the lines are broadened, shifted, and exhibit asymmetric intensity profiles. Measurements of the shift of some lines as a function of relative density of the perturbing gas are presented, and observations of diffuse, satellite bands on the short wavelength side of some of the atomic lines are reported.
