Abstract:

The calculations of the rate coefficients for dielectronic recombination (DR) along the CuI isoelectronic sequence in the ground state Au⁵⁰⁺ are performed using the model of spin-orbit-split arrays(SOSA). The trend of the DR rate coefficients is founded with the changing of the electronic temperature in the range of 0.02～5?keV. The main factors which put effects on the DR coefficients are the principal quantum numbers of the relative spectator electrons, the relative auto-ionization coefficients and auto-ionized energy. All the mentioned above will provide some important parameters for diagnosing the palasmas.

Key words: dielectronic recombination coefficients, autoionization coefficients, radiative coefficients
