Abstract:

The dielectronic recombination (DR) rate coefficient for neon-like xenon in the ground state has been performed using relativistic configuration interaction (RCI) method over a wide temperature ranging from 0.01EI to 10EI (EI=3332eV), where EI is the ionization energy of the Na-like xenon. The results show, the domain contribution comes from (2s2p)73ln′l′ series, which is about 90％ of the total DR rate coefficient, in which the main contribution comes from (2s2p)73l3l′ and (2s2p)73l4l′ configurations, and the proportion is more than 70％ of the DR rate coefficient for (2s2p)73ln′l′ complex. The contribution of (2s2p)73ln′l′ complex with l′>8 are found to be negligible. The contribution of high Rydberg states of (2s2p)73ln′l′ complex obeys the complex-complex n′-3 extrapolation.
