Abstract: The line radiation of multiply charged ions with a Fermi–Dirac level distribution of electrons is investigated in the plasma temperature range where the motion of electrons may be treated as quasi-classical, and the potential in which they move, as Coulomb, which is valid under the conditions $ZE_H\ll\max(T, \hbar\omega_l)\ll Z^2E_H$, where $E_H=13.6$ eV is the ionization energy of hydrogen, $Z$ is the atomic number of the ion being treated, and $\omega_l$ is the frequency of electron reversal in the Coulomb field at an energy equal to the ionization energy. The spectrum and intensity of radiation of ions are calculated. In the limit of high plasma densities, the intensity of radiation per ion turns out to be independent of density and proportional to $T^2$.
