X-ray absorption via electron-ion bremsstrahlung in Maxwellian plasma at the exact consideration of Coulomb potential

Based on the results of exact consideration of electron-ion Coulomb interaction, by numerical simulations for ultimate absorption coefficient, we study the practically more interesting case of absorption of hard x-ray quanta of frequency when photon energy is of the order of plasma temperature, in high temperature plasma, within the high nuclear charges as well (at which the Born approximation is not applicable), constituting the temperature dependence of one-photon absorption coefficient. It is shown that one can achieve the efficient absorption coefficient in these cases.
