This paper uses a formula derived by Karzas and Latter (1961) for the photoionization cross-sections of the hydrogen atom as a basis for a numerical
computation of the radiative recombination coefficients. Tables of the
computed results are given for all angular momemtum states up to and
including <i>n</i> = 10, <i>l</i> = 9 over a temperature range of from 10<sup><font size="1">3</font></sup> °K to 10<sup><font size="1">6</font></sup> °K.

<b>Summary.</b> The statistical equilibrium equations of the <sup><font size="1">3</font></sup><i>P</i><sub><font size="1">0, 1, 2,</font></sub> 
<sup><font size="1">1</font></sup><i>D</i><sub><font size="1">2</font></sub> and
<sup><font size="1">1</font></sup><i>S</i><sub><font size="1">0</font></sub> 
levels of the ground 3<i>s</i><sup><font size="1">2</font></sup> 3<i>p</i><sup><font size="1">2</font></sup>
configuration of Fe<sup><font size="1">+12</font></sup> have been solved
for the ranges of electron temperature, electron density and geometrical
dilution factor believed to be relevant to Fe XIII emission from the solar corona. Direct collisional and radiative transitions
between these levels and indirect collisional excitation of allowed
transitions to the 
3<i>s</i> 3<i>p</i><sup><font size="1">3</font></sup>
and
3<i>s</i><sup><font size="1">2</font></sup> 3<i>p</i> 3<i>d</i>
configurations followed by radiative decay to the ground configuration
are taken into account using new atomic data calculated in intermediate
coupling allowing for the effects of configuration interaction. Particular
attention is paid to assessing the remaining uncertainties in the atomic
parameters. The indirect process is found to be the dominant collisional
process in the statistical equilibrium equations. The variation of the
λ 10747/λ 10798 and λ 3388/λ 10747 line intensity ratios are presented
as functions of electron density and consistent values of the electron
density of the emitting region are obtained when the calculated intensity
ratios are combined with existing observations. </p>

<p>These comprehensive spectroscopic data tables for the spectra of highly ionized
heavy atoms provide a valuable resource for researchers who need detailed
spectroscopic information on energy levels, wavelengths, ionization energies,
and oscillator strengths. Critically evaluated data for these spectroscopic
quantities, both observed and calculated, are tabulated for the elements Ti, V,
Cr, Mn, Fe, Co, Ni, Cu, Kr, and Mo. The tables include data for all stages of
ionization from Ca-like through H-like spectra, except for Kr and Mo which start
at Ge-like and Rb-like, respectively. Typically, several hundred transitions are
covered for each spectrum. The tables are arranged in order of decreasing
wavelengths, and lines belonging to the same multiplet are grouped together. Forbidden lines, i.e., mainly magnetic dipole (M1) and electric quadrupole
(E2) transitions are also included and are identified as such. A unified finding
list, in which lines are ordered according to wavelengths, contains all the
tabulated transitions. Short reviews on the line identifications and wavelength
measurements are given for each stage of ionization. The general introduction
contains a discussion on the method of evaluation and some background on the
compilations.</p>
