Abstract
Energies, wavelengths, transition probabilities, and oscillator strengths have been calculated for the 4s(2)4p(2) - 4s4p(3), 4s(2)4p(2) - 4s(2)4p4d and 4s4p(3) - 4p(4) allowed transitions in heavy Ge-like Sm and Eu ions. The fully relativistic Multiconfiguration Dirac-Fock (MCDF) method taking into account both the correlations within the n = 4 complex and the quantum electrodynamic (QED) effects have been used in the calculations. MCDFGME code is used to calculate electron impact excitation cross sections for the 4s(2)4p(2) - 4s4p(3), and 4s(2)4p(2) - 4s(2)4p4d transitions with plane-wave Born approximation. The results of Sm XXXI and Eu XXXII are compared with HFR method results.
