T. Efthimiopoulos et al., EXCIMER EMISSION-SPECTRA OF RARE-GAS MIXTURES USING EITHER A SUPERSONIC EXPANSION OR A HEAVY-ION-BEAM EXCITATION, Journal of physics. D, Applied physics, 30(12), 1997, pp. 1746-1754
Results related to the energy transfer in the rare gas mixtures are re
ported for an electrical discharge excitation with plasma expansion an
d a heavy-ion-beam excitation. Energy transfer from the lighter rare g
ases to the heavier ones was observed in a very efficient way for both
excitation mechanisms. Strong emission from excited atomic states, wh
ich are possible candidates for new lasers, was observed for the elect
rical discharge case. The broad-band emission of the discharge sources
makes them appropriate for strong lamps in the VUV. Some comparisons
of the two excitation mechanisms were discussed with respect to the en
ergy deposition, the density of dimers and their vibrational relaxatio
n.
