Abstract:

A brief description is given of the shock tube facility and associated measuring equipment. The theory of radiative transfer in a uniform gas is developed with reference to shock tube spectroscopic measurements. Gas temperatures behind reflected shocks were measured simultaneously by a line reversal technique and by an ultrasonic probe method. The average temperatures agree to within 3-12. Measurements of shock gas density were made with an electron beam gas densitometer. A set of preliminary gf values were determined for ten CrI spectral lines distributed over three multiplets.
