A nonhydrogenic single‐electron‐transition model with Dirac‐Slater SCF wavefunctions and all necessary multipoles has been used to obtain partial photoionization cross sections for C 3+ , O 5+ , Al 10+ , Fe 23+ , and Mo 39+ for principal quantum number n = 10 and all l, hv ⪖ 200 keV, supplementing results reported elsewhere for n = 2, 3, 4, and 6. The partial cross sections for the isoelectronic sequence are represented approximately by a simple analytical form: ln[( Z — s nl ) 2 σ nl ( hv )] = Σ 3 0 ai(nl)x i . ( Z is the nuclear charge, x = ln [ hv /( Z — 2) 2 ].) n ‐3 scaling is used to obtain partial cross sections for other values of n (6 < n < 10, 10 < n < 100). Radiative recombination rate coefficients (summed over l and n < 100) have been calculated from the partial photoionization cross sections for kT = 0.01, 0.03, 0.1, 0.3, 1.0, 3.0, and 10.0 keV. The results have application to ionization balance calculations for the solar corona and for Tokamaks.
