Theoretical calculation of transition probabilities and lifetimes of levels of the 4d(9)5p configuration of CdIII

The configuration superposition method realized in the basis of Hartree-Foc k functions and transformed radial orbitals with variable parameters is app lied to ab initio calculation of electronic transition probabilities from l evels of the 4d(9)5p configuration of the CdIII ion. Relativistic correctio ns in the energy spectra are calculated within the framework of the Hartree -Fock-Pauli approximation, i.e., in the second order in the fine structure constant. The inclusion of correlation and relativistic corrections makes i t possible to achieve a good coincidence of the values of electric dipole t ransition probabilities calculated with the use of two forms of the operato r-the form of length and the form of velocity-for both strong and weak tran sitions. Using the transition probabilities obtained, radiative lifetimes o f levels of the configuration indicated are determined. They are in a good agreement with the currently available experimental data.
