Abstract

Radiative recombination rate coefficients (RRC) are presented for several ions with open and closedshells, ( H I, He I, He II, N V, N VI, N VII) . The temperature of electron range 10-109 K is considered.The calculations have been performed in the framework of analytic fit parameters formula with noconsideration of relativistic effects. Our results of RRC compared with the theoretical data available as afunction of electron temperature, and the agreement was very good. Some data which had been dependedshowed a peak at high temperatures because of the influence of autoionizing resonance.
