The energy levels, wavelengths, transition rates, and oscillator strengths have been calculated for the fine-structure levels of the 4 s 2 4 p 2 , 4 s 4 p 3 , 4 s 2 4 p 4 d , and 4 p 4 configurations in Ge-like Mo, Ru, and Rh ions. The fully relativistic multiconfiguration Dirac–Hartree–Fock method, taking correlations within the n  = 8 complex, the Breit interaction and the quantum electrodynamics effects into consideration have been used in the calculations. Valence and core–valence electron correlation effects are accounted for through single–double multireference (SD-MR) expansions to increasing sets of active orbitals. Our results are compared with available experimental and other theoretical results, and a good agreement is obtained.
