DIELECTRONIC RECOMBINATION TO THE EXCITED-STATES OF BE-LIKE FE IONS

Energy level (E), radiative transition probability (Ar), and autoioniz ation rate (Aa) for Be-like Fe22+ ion are calculated with use of Cowan 's code. Using these atomic data, the dielectronic recombination rate coefficient (alpha) to the excited states and the intensity factor (Qd ) of the dielectronic satellite lines have been calculated. The doubly excited states 1s(2)3lnl' as well as the 1s(2)2pnl are considered. Th e results are given in tables and figures. The n- and l-dependence for Ar, Aa, and a is studied. With use of it, Aa and Ar at large n are ex trapolated. The dielectronic recombination processes from the 1s(2)2pn l and those from the 1s(2)3lnl' dominate at low and at high temperatur e, respectively. The comparison of the dielectronic recombination proc esses for Fe22+ and C2+ ions is discussed in order to understand the a tomic nuclear charge scaling. The qualitative different behaviors for E, Ar, and a between Be-like ions and He-like ions are also discussed with use of atomic nuclear charge scaling.
