A large-scale relativistic configuration-interaction calculation for the 4s-4p transition energies of copperlike heavy ions

摘要

The 4s-4p transition energies for high-Z copperlike ions are calculated using the relativistic configuration-interaction(RCI)method.These calculations are based on the relativistic no-pair Hamiltonian which includes Coulomb and frequency-dependent,retarded Breit interactions and use B-spline orbitals as basis functions.Mass polarization and quantum electrodynamic(QED)corrections are also calculated.The present RCI energies agree very well with results from the relativistic many-body perturbation theory.With QED corrections included,our total transition energies are in very good agreement with recent high-precision measurements.
