Physical Models of Plasma Microfield

Figure 18

Reduced values of longitudinal and perpendicular second moments according to [170, 171]: dashed curves correspond to Chandrasekhar and von Neuman results [19–21] for fixed velocity values of test particle; solid curves are erroneous results [170, 171] with account of Doppler broadening (see [170]); the upper curves according to [170, 171] correspond to 𝑁=10¹⁷ cm−3, 𝑇=12700 K, and lower curves to 𝑁=3 1017 cm−3, 𝑇=14800 K; dotted curves the results that account for Debye screening due to authors [170] statements; the axis of abscisses shows the reduced microfield values.
