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.
