Abstract

Hydrogen gas at 0.25 mbar is led through a quartz tube and dissociated to atomic hydrogen at the surface of a filament, which is electrically heated. Around the filament is a titanium mesh containing potassium, which acts as a catalyst. When the atomic hydrogen is in contact with the catalyst a plasma arises and Lyman and Balmer emission by the hydrogen atoms takes place. We have analyzed the H~ emission profile of our experiment by fitting Voigt functions. The first results give for TH 0.2 eV and for n~ 2.1013 cm3.
