摘要：

Doppler broadened H(gamma) emission was detected in high frequency (350 and 500 MHz) hydrogen surface wave sustained discharges, revealing the presence of fast excited H atoms with kinetic energies in the range 4-9 eV. Spatially resolved measurements of the Doppler-broadened emission indicate that these fast atoms are predominantly formed near the wall, which suggests that their generation may result from acceleration of H(+) ions in the radial dc space charge field followed by recombination at the wall and the return of the neutral atom to the gas phase.
