Abstract
We have performed fully relativistic Dirac–Fock calculations of total cross sections for radiative recombination of heavy element impurities with electrons and subshell photoionization cross sections for 31 ions of Fe, Ni, Cu, Mo, and W, which are important elements in plasma studies. The electron kinetic energy range is 4 eV to 50 keV. To obtain the total radiative recombination cross section, subshell cross sections were calculated for ground and all excited electron states up to states with principal quantum number n = 20. The total radiative recombination cross sections are presented in tabular and graphical forms. The subshell photoionization cross sections for excited states with n ⩽ 12 and orbital momenta ℓ ⩽ 6 were fitted by a simple analytical expression with five fit parameters. The fit parameters are tabulated.
