Abstract

The main purpose of this work is to calculate the radiative, dielectronic and total recombination of non-hydrogenic elements. We applied the photoionization codes to investigate the recombination coefficients. We have calculated radiative and dielectronic recombination coefficients of some elements at different temperatures and ionization stages. The results are obtained at low temperatures between 5,000 and 20,000 K and it shows that the dielectronic coefficients are not negligible relative to radiative recombination by assuming the solar abundances of H, He, C, N, O, Ne and S. We determined the total recombination coefficients of each element and compared them with previous works. Our calculations the radiative dielectric and total recombination coefficients of oxygen, nitrogen, carbon, neon and sulphur ions at a given temperature agree with the previous works.
