Abstract:

The ionization process in xenon has been studied by measurements of the atomic line radiation histories. Visible line radiation measurements of three atomic line transitions resulted in the measurement of time resolved bound electron temperature. No conclusion can be drawn with regard to the non-Boltzmann behavior of the bound states due to the inaccuracies in the reported transition probabilities. Resonance radiation histories are similar to those in the visible. Static pressure profiles clearly define the shock front while total pressure profiles clearly define ionization and test times.
