“…Kreye and Kreye/Kielkopf [6][7][8][9] have used the ( ) g s terms to compute spectral-line shapes for the line core; and from them have measured the w 's and the shifts d 's of the 5802 Å line for the Ar-perturber/K-radiator system at temperatures (T's) equal to 400, 800 and 1000 K. In the present paper, Kreye extends the previous studies [6][7][8][9] as follows:(1) the g(s) term from the newly derived unified theory of spectral line shapes Eq. (121) [4] is put into a computable form and the w 's are measured from the computed line shapes for the line core;(2) a computed nonimpact-approximation curves for the unified theory are studied at T=400 and 1000 K and compared with those from non-impact-approximation theory; (5) a question had been brought up in the previous paper [9], which shows in Fig.…”

In a recent publication, a new unified theory of spectral line shapes was derived, which allowed for the variation of the electric dipole moment with perturber positions. The present author put the () g s term derived from the theory into a computable form, and constructed spectral line shapes from which line-core HWHM's () w s ′ were measured. These w 's were compared with experimental Fabry-Perot-interferometric results.

Quantum-mechanical and semi-classical spectral-line shapes are computed at , , and K for the line core of the 5802 Å line of the Ar-Perturbed/K-Radiator system. HWHMs ('s) are measured from computed full spectral-line shapes. The final-state pseudopotential is for the state, and the initial-state potential is for the state. Three high-pressure (P) —versus— curves, corresponding to the non-impact region, intersect a similar set of low-P, impact-region curves at intersections, 's. Similarly, for two sets of —versus— curves, which yield intersections, 's, where is the perturber density. These 's and 's separate the two regions and represent the upper limits of the impact regions. A specific validity condition for the impact region is given by the equation . From an earlier spectroscopic, Fabry-Perot paper, cm−1 at K and torr. Two theoretical values, and cm−1 corresponding to two different pseudo-potentials, are reported. Two -dependent figures are given, in which the first shows an increase in the impact region with , based on as the basic parameter, and the second which shows a decrease in the impact region with , based on as the basic parameter.
