(a) Electron-ion and electron-neutral inverse bremsstrahlung cross-sections, \(\sigma _\mathrm{IB,EI}\) (blue) and \(\sigma _\mathrm{IB,EN}\) (red), as a function of electron temperature. (b) Electron-ion and electron-neutral inverse bremsstrahlung absorption coefficients, \(\alpha _\mathrm{IB,EI}\) (blue) and \(\alpha _\mathrm{IB,EN}\) (red), as a function of electron temperature. For the calculation of the coefficient, \(n_{\textrm{e}}\,=\,10^{23}\)/m\(^3\) and \(n_\mathrm{n}\,=\,1.8\times 10^{25}\)/m\(^3\) were used.
