Relativistic atomic data for lines in Ge-Like Sm and Eu ions

Abstract

Energies, wavelengths, transition probabilities, and oscillator strengths have been calculated for the 4s24p2 - 4s4p3, 4s24p2 - 4s24p4d and 4s4p3 - 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 24p2 - 4s4p3, and 4s24p2 - 4s24p4d transitions with plane-wave Born approximation. The results of SmXXXI and Eu XXXII are compared with HFR method results.
