Abstract
The charged-particle density found from the Stark broadening of spectral lines in an inhomogeneous plasma source can be attributed with an error of 10–15% to regions of maximum spectral brightness of the line center. If the contour is recorded under conditions such that the spectral brightness of the line center is much greater than that of the wings, the experimental results can be attributed to the central regions of the inhomogeneous source. If, on the other hand, the contour is recorded under conditions such that the spectral brightness of the line center exceeds the measured spectral brightness of the wings only slightly, the experimental results should be applied to the periphery of the inhomogeneous source.
