Abstract:
We have calculated partial final-state resolved radiative
recombination (RR) rate coefficients from the initial ground and
metastable levels of all elements up to and including Zn, plus Kr, Mo,
and Xe, for all isoelectronic sequences up to Na-like forming Mg-like.
The data are archived according to the Atomic Data and Analysis
Structure (ADAS) data class adf48, which spans a temperature range of
z2(101-107)K, where z is the initial ion charge. Fits to total
rate coefficients have been determined, for both the ground and
metastable levels, and those for the ground are presented here.
Comparison is made both with previous RR rate coefficients and with
(background) R-matrix photoionization cross sections. This RR database
complements a dielectronic recombination (DR) database already
produced, and both are being used to produce updated ionization
balances for both (electron) collisionally ionized and photoionized
plasmas.

1- 2 I2 --- Z Nuclear charge
4- 5 I2 --- N Number of ion electrons before recombination
7- 15 E9.3 cm3/s A Total RR rate coefficient "A" (1)
17- 22 F6.4 --- B Total RR rate coefficient "B" (1)
24- 32 E9.3 K T0 Total RR rate coefficient "T0" (1)

44- 49 F6.4 --- C ? Total RR rate coefficient "C" (1)
51- 59 E9.3 K T2 ? Total RR rate coefficient "T2" (1)
--------------------------------------------------------------------------------
Note (1): Total RR rate coefficients, for both ground and metastable
initial levels, are fitted to the usual functional form, viz,
αrr(T)=A[sqrt(T/T0)*[1+sqrt(T/T0)]1-B*[(1+sqrt(T/T1)]1-B]-1
where, for low-charge ions, B is replaced as B --> B+C.exp(-T2/T)
