Scientific paper

Oscillator strengths of seven lines of neutral nitrogen, belonging to the strong vacuum-ultraviolet multiplets at 1243, 1493, and 1743 A, are measured in emission with a wall-stabilized arc burning in argon at normal pressure, to confirm the f-values of the lines belonging to these multiplets. The self-absorption of radiation in the plasma is taken into account while the use of a growth curve is avoided. Demixing effects are also avoided by calibrating the relative oscillator-strength scale with a known absolute f-value. All the investigated lines are shown to be saturated by increasing the nitrogen concentration, and the technique allows the separation of overlapping lines and the determination of the extended wing contribution. The study reveals oscillator strength value uncertainties of between + or - 12 and + or 20 percent.
