Contribution of near threshold states to dielectronic recombination in recombining plasma with Li-like Al ions

The dielectronic recombination of Li-like into Be-like aluminum ions, in laser-produced plasmas with Li-like ions, is re-visited with respect to the contribution of near-threshold states. Results are shown for recombining laser-produced plasma regime. The relativistic Dirac R-matrix calculation is performed to output resonance energy levels and rates. The target energies, and orbitals, are calculated with the extended average level multi-configurational Dirac-Fock method in the general-purpose relativistic atomic structure package (GRASP), while for determining the plasma population densities distribution over the excited Rydberg states, the Atomic Data Analysis System (ADAS) package programs is used.
