Calculated level energies, transition probabilities, and lifetimes of silicon-like ions

摘要: The authors present theoretical excitation energies and lifetimes for the 27 low-lying levels of silicon-like ions S, Ar, Ca, Ti, Fe, Zn, Kr (16 {le} Z 36). Special attention has been paid to provide a complete tabulation all electric-dipole (E1) allowed transitions from 3s3p{sup 3} 3s{sup 2}3p3d excited configurations those 2}3p{sup 2} ground-state configuration, including weak intercombination transitions. Large-scale multiconfiguration Dirac-Fock wave functions are applied compute transition probabilities. They further investigate decay 2}3p3dJ = 4 level which is connected configuration only via forbidden M2 but otherwise mainly decays M1 lower-lying same parity. For few selected data, they compare results with experiment previous computations.
