Non-Equilibrium Radiation from Shock Heated Nitrogen and a Determination of the Recombination Rate
Abstract
The radiation emitted by shock heated nitrogen in the wavelength range 3300 to 7100 angstrom units at an equilibrium temperature from 6000 to 6800 K and densities from .01 to .20 atmospheres. The various radiating bands are identified by spectroscopic and photometric techniques. The radiation consists of bands from various nitrogen systems. The radiation overshoot observed at the shock front relaxes very rapidly to a equilibrium level. Comparison is made between the calculations and observations. It is concluded that one of the coupling schemes is a realistic approximation. The integral non-equilibrium radiation and the time of occurrence of peak radiation behind the shock front are also examined.
