Fig. 1. Variation of the electron part of the dynamic plasma form-factor spectrum with changes in parameters that influence α: (a) scattering angle; (b) plasma temperature; (c) and (d) plasma density. The incident radiation frequency ω_i = 2 eV.

Fig. 2. Spectra of incident pulses with various durations (red curves) and differential scattering cross-section at T_e = 2 eV, n_e = 10¹⁷ cm⁻³, ω′ = 2.1 eV, and θ = π/4 (blue curves).

Fig. 3. Dependence of the differential scattering probability on the pulse duration for different values of the carrier frequency. Different trends are illustrated in the different panels: (a) a bell-shape maximum with an asymptote tending to zero; (b) a monotonic rise; (c) and (d) a nonmonotonic rise, tending to the linear regime. The parameter values are T_e = 2 eV, n_e = 10¹⁷ cm⁻³, ω′ = 2.1 eV, and θ = π/4. Solid lines correspond to calculation using the formula (3.3) and dashed lines to calculation using the approximations (4.7) and (4.9).
