[en] The energy levels and transition properties of In-like ions are investigated by using the multi-configuration Dirac–Hartree–Fock method. The results for the energy levels, transition probabilities, wavelengths, line strengths and lifetimes of In-like Cs VII—Pm XIII are reported. Relativistic effects and electron correlation are included. The calculations obtained agree well with the experimental and other theoretical values. The new data of energy levels and transition parameters are predicted. The level crossing happens between the configurations 5s 24f and 5s 25p with increasing nuclear charge. The transition frequencies are within the range of usual lasers because of the level crossing. In-like ions may be developed into atomic clock. (author)
