Noble gas plasmas operate easily in the high-frequency range.
The gas was ultrahigh-purity hydrogen or noble gas-hydrogen mixture (90/10%) at 2 torr total pressure.
The argon analysis was performed using the isotope dilution procedure on a noble gas mass spectrometer in duplicate.
In none of these plasmas was there any significant broadening of the noble gas lines.
Femtosecond time resolved studies of the dynamics of noble gas cluster explosions.
Finally, palaeotemperature studies are outlined, which use the temperature dependence of noble gas solubility.
No other species in these plasmas, specifically molecular hydrogen and various noble gas species, were found to be 'hot'.
This is usually the case when the dust is embedded in a noble gas without impurities.
