Calibration of the width of the NI spectral line at [formula omitted] for electron density determination

The Stark broadening of a NI spectral line at 7915.42 A ̊ has been calibrated for electron density determination of low temperature plasmas. The determined simple formula based on measured FWHM is applicable in the electron density range from 3×10 15 to 10 16 cm −3 .
