Energy Levels, Wavelengths and Life Time for Transitions in Ag XIV

摘要

Atomic parameters were estimated for the 4s² 4p⁴, 4s 4p⁴ 4d, 4s 4p⁵, 4s² 4p³ 4d and 4s² 4p³ 4f configurations for electric quadrupole (E2) and magnetic dipole (M1) transitions occurring within the ground configuration (4s² 4p4) in the heavy atom of laboratory and astrophysical interest. The fully relativistic multi-configuration Dirac-Fock method taking into account both the correlations within the n = 4 complex and the QED effects has been used for the calculations. The obtained results are compared to those done by Hartree-Fock method and agree well with recent electron-beam ion-trap measurements. This has led to an accurate determination of scaling factors for the Slater and spin-orbit integrals calculated by the Hartree - Fock method. Predicted wavelengths and line strengths are given for Ag XIV. Results for fine structure energy levels and oscillator strengths and transition probabilities, life time, cross section and transition wavelengths (λ) are listed for all strong E1, E2 and M1 transitions among the 38 levels of Ag XIV ion.
