To make … Witryna14 lip 2024 · where \(I_{k}\) and \(R_{k}\) are the ionization and recombination rate coefficients, respectively. In the coronal model, ions are excited by collisions with electrons and immediately decay into the ground state. The recombination rate \(R_{k}\) is the sum of radiative recombination, dielectronic recombination and three-body …
