摘要: The 2P1/2–2P3/2 fine structure transitions in the ground (np5) state of neon (n=2) and argon (n=3) atomic ions have been observed absorption positive column a liquid–nitrogen cooled discharge cell, by employing tunable infrared diode lasers as sources. transition frequencies were measured to be 780.4240±0.0011 1431.5831±0.0007 cm−1 for Ne+ Ar+, respectively. A few also neutral Ne Ar atoms.
