Abstract
The wavelengths have been measured for 200 lines of N I in the long-wave region and 71 lines in the vacuum-ultraviolet region. The latter have also been calculated from the recalculated system of energy levels. The designations 6s2P3/2, 4d4D5/2, 4P5/2, 3/2, 1/2, 2F5/2, and 5d4D5/2, 4P5/2, 1/2 have replaced the previous designations 6s2P1/2, 4d4P5/2, 2F5/2, 4P1/2, 3/2, 4D5/2, and 5d4P5/2, 4D5/2, 4P3/2, respectively. The new levels 6s2P1/2, 4p2D5/2, 3/2, 2P3/2, 1/2, 5p4D7/2, 5/2, 3/2, 1/2, 4P5/2, 3/2, 1/2, 4S3/2, 2P3/2, 1/2, 2S1/2, 4d4D7/2, 3/2, 1/2, 5d4F3/2, 4D7/2, 3/2, 1/2, 4P3/2, and 6d4F9/2, 7/2 have been established. The limit 2s22p23P2 has been determined to 117 356.46±0.12 cm-1.
