| Abstract | ||
| The electron-ion collisional radiative recombination for electron temperatures (10-109) Ko have been investigated, using a new analytic fitting formula. Ionization balance in the low ionization stages of systems is important in a variety of astrophysical plasmas. Accurate recombination rates are needed but are difficult to compute in a detailed quantum mechanical treatment. The main difficulty lies in the complexity of strong electron-electron correlation. We present the electron-ion recombination rate coefficients for the electron interacting with (C I, C II, N II, O III, F IV, Ne V, Si IX, S XI) ions sequence. Our results of radiative recombination rates coefficients have compared with the available data in which depend the close coupling approximation using the R-matrix method employing a unified treatment, that considers the infinite number of states of the recombined ion and incorporates both the radiative recombination and the dielectronic recombination processes in a self-consistent manner. | ||
