Abstract Spectroscopic studies of the dark space ahead of a detached shock wave caused by a blunt body were made in a partially ionized argon flow. From emission measurements, spatially resolved population densities of states 5p[3/2], 5p[5/2] and 4p[3/2] were determined at 20 stations in the flow, for both cases when the blunt body is placed in the flow and when it is withdrawn. The result shows that the population densities of the above mentioned states ahead of the shock wave are reduced when the body is placed in the flow. A prediction was obtained by assuming a steady state population for all levels higher than level 4 s. In the prediction the measured electron temperatures and densities were employed to determine collisional transition probabilities. From a comparison of the experiment with the prediction, it is considered that the dark space is caused by the elevation in the electron temperature ahead of the shock wave.
