Balmer-Line Anomalies in a Turbulent Plasma

Resonance effects between orthogonal components of dynamic and quasistatic electric fields within a turbulent hydrogen plasma are shown to produce satellites on the H_β profile. The splitting on H_α, H_β, H_γ, and H_δ profiles indicates that the quasistatic field strength is 0.9 ×{} 10⁷ V/m. By using a helium tracer, comparison of a forbidden transition with its satellites indicates that the dynamic field (at the plasma frequency) is 1.3 ×{} 10⁷ V/m.
