Summary:The most up-to-date photorecombination spectrum of Ga 13+ and Ge 14+ has been re-assessed with direct large-scale relativistic atomic structure calculations. The new temperature-dependent dielectronic recombination rate coefficients are presented in a form convenient for astrophysical plasma modeling, summarizing the importance of different multi-electron intra-shell core excitations in the target ions. Obtained results are expected to facilitate a more accurate determination of the ionization-recombination balance of multiply-charged gallium and germanium ions and to improve the diagnosis of the radiative energy loss rates from low-density high-temperature plasmas. ►Relativistic atomic structure calculations. ►Documenting the extent of various core excitations in target ions. ►Pertinent to electron-ionized and photo-ionized laboratory plasmas.
