Temperature Dependences of the Quantum-Mechanical and Semi-Classical Spectral-Line Widths and the Separation of the Impact and Non-Impact Regions for an Ar-Perturbed/K-Radiator System
Figure 2
Plots of โversusโ in the two pressure regions: The high-P, non-impact region (104.5 to 106 torr); and the low-P, impact region (103 to 105โtorr). Three sets of curves are presented at (counting down) 400, 800, and 1000โK. The QM curves are solid lines, and the SC curves are dashed lines in both regions. The dotted lines are approximate extrapolations from the QM non-impact curves. The intersection of an extrapolation with the corresponding QM impact-region curve, represented by an , gives rise to , the approximate separation between the impact and the non-impact regions.
