Kinetic Spectroscopy in the Far Vacuum Ultraviolet
Part 5. Oscillator strengths for the 3s, 4s, 5s, 3d and 4d 4PJ - 2p 3 4S
A discharge-flow system, incorporating a windowless resonance cell, has been used to generate known concentrations of ground-state 2p3 4S3/2 0 nitrogen atoms. Resonance-absorption measurements for the N 4PJ-2p3 4S3/2 0 transitions with upper-state 3s, 4s, 5s, 3d and 4d configurations have been made as a function of ground-state nitrogen atom concentration. The results gave the following values for the oscillator strengths (Σgkfik) of these transitions of N: transition wavelenght/nm Σgkfik 3s4P j-2p 34S3/2 0 120.016 (1.04 ± 0.21 4s4Pj- 96.456 (0.065 ± 0.020) 5s4Pj- 91.019 (0.018 ± 0.006) 3d4P j- 95.325 ≥ (0.024 ± 0.008) 4d4Pj- 90.612 (0.013 ± 0.006) This appears to be the first experimental determination of the oscillator strengths for the 4s, 5s, 3d and 4d transitions. Agreement of the present Σgkfik value for the 3s-2p3 transition of N with previous work is good.
