ENERGIES AND SPECTRAL LINES FOR THE STATES OF 4s24p2, 4s4p3, and 4s24p4d CONFIGURATIONS IN Ge-LIKE Te, Xe, and Ba IONS
Abstract
The energy levels, wavelengths, transition rates, and line strengths have been calculated for the 4s24p2-4s4p3 and 4s24p2-4s24p4d allowed transitions occurring within the ground configuration (4s24p2) in the heavy Ge-like Te, Xe, and Ba ions. The fully relativistic multiconfiguration Dirac-Hartree-Fock method taking into account both correlations within the n = 5 complex and the QED effects has been used in the calculations. The calculation results are found to agree well with the data obtained on the TFR tokamak and by recent EBIT measurements in Xe. The isoelectronic sequence of the Ge-like ions is important in nuclear fusion research as their spectra may provide diagnostic information on magnetically confined plasmas.
