摘要：

The light absorption coefficient is evaluated in strongly coupled plasmas. Analysis is based on the calculation of the dynamic collision frequency of electron-ion scattering. Under plasma conditions when electron scattering has quantum character, the Born approximation for screened electron-ion interaction is used. In the case of classical scattering non-Born corrections become essential at high frequencies. Interpolation formulas for the collision frequency and Gaunt factor are presented at intermediate frequencies. Theoretical calculations are compared with measurements of bremsstrahlung for dense Ar and Al plasmas and computer simulation data.
