Abstract

Relativistic perturbation theory has been applied to the calculation of the energies of 2lj2l'j'[J] states in the range of Z = 10-100. The non-diagonal elements for non-degenerate states are discussed. Numerical results were obtained in the intermediate coupline scheme. The intermediate coupling coefficients were used for calculation of autoionization widths. The decay amplitudes for 2lj2l'j'[J] are calculated with Dirac functions. The influence of relativistic effects on the autoionization widths is discussed.
