Measured stark widths and shifts of several N III spectral lines: Temperature dependence

Abstract

Stark parameters (width and shift) of four doubly ionized nitrogen spectral lines, that belong to 3s-3p and 3p-3d transitions (lower multiplets), have been measured in a linear pulsed, low pressure, arc discharge in the nitrogen-oxygen and helium-nitrogen-oxygen plasmas in a (30 000 - 54 000) K electron temperature and a (0.75 1023 - 2.8 1023) m-3 electron density ranges. The measured values have been compared to the existing experimental and calculated data.
