Abstract

Relative transition probabilities of 81 infrared Ar i lines in the wavelength range from 9000–24 000 Å have been measured with a wall-stabilized arc operating in argon at atmospheric pressure. The large majority of the lines from the 4p–5s and 4p–3d transition arrays has been observed and the measurements are consistent with the J-file-sum rule. The data have been normalized to an absolute scale by utilizing the results of other recent arc and lifetime experiments.

Paschen notation is used for the levels. Values in parentheses are rough experimental estimates (for partly blended or weak lines) and values superscript a are from the intermediate coupling calculations of Murphy.30 The numbers given in italics in the lower-right corner are the sums ∑2J + 1 and ∑(∑S).
