The nonthermal and screening effects on the Thompson scattering process are investigated in generalized Lorentzian electron plasmas. The Thompson scattering cross section is obtained as a function of the spectral index, wave number, and Debye length. It is shown that the nonthermal effect suppresses the Thompson scattering process in Lorentzian plasmas. It is also shown that the nonthermal effects on the forward scatterings are more significant than those on the backward scatterings. In addition, the nonthermal effects are found to be more significant in the intermediate domain of the wave number.
