Abstract:

A study of the structure of electromagnetically produced shocks has been made which illustrates a technique for measurements of either photoionization cross sections or number densities of plasma particles. This technique utilizes measurements of intensity ratios, due to plasma absorption of ultraviolet radiation which is governed by the Lambert-Beers law. Due to the complex band structure of diatomic molecules, this experiment used instead a rare gas, xenon, to study number densities of Xe and Xe Plots of neutral and ion densities as a function of time show clearly the shock front defined by a rise in particle density. Relaxation times and effects due to precursors were also studied. Author
