Total cross sections for radiative recombination with an electron for 36 ions of Si, Cl, Ar, Ti, Cr, Kr, and Xe as well as subshell photoionization cross sections are presented. The electron kinetic energy is {<=}50 keV. The calculations were performed using the relativistic Dirac-Fock method and the results have been included in a database of radiative recombination and photoionization cross sections for the heavy element impurity ions occurring in plasmas. The data are required for modelling fusion and astrophysical plasmas. To obtain the total radiative recombination cross section, calculations have been carried out for ground and all excited electron states up to states with the principal quantum number n = 20. The subshell photoionization cross sections for all states with n {<=} 12 and orbital momenta l {<=} 6 have been fitted by an analytical expression with five fit parameters which are tabulated.
