Temperature Dependences of the Quantum-Mechanical and Semi-Classical Spectral-Line Widths and the Separation 𝑛₀ of the Impact and Non-Impact Regions for an Ar-Perturbed/K-Radiator System

Figure 5

This plot shows the 𝑃₀—versus—𝑇 curve, where the 𝑃₀ intersections are taken from Figure 2. This curve establishes that the impact region, defined by 𝑃₀, increases with increasing 𝑇 when 𝑃 is the basic parameter.
