Collisional Excitation using Metastable Helium Jet Produced in a Graphite Tube Nozzle
Iek Soon Choi, Young Mi Ha, Sang Kuk Lee*
The graphite tube nozzle has been developed for the generation of metastable He jet by which the nitrogen molecules initially excited in a jet with Engelking type nozzle have been further excited in a corona excited supersonic expansion. The excitation process of nitrogen molecules in the jet collision has been discussed in detail by observing the emission intensity from the vibronic emission spectra of nitrogen molecules and nitrogen molecular ions upon helium jet collision.
