Highly Excited Autoionization States of Li-like Ions: I. Level Energies

摘要

The energies of the levels of the 1s2lnl ' (n = 2–10, l ' = 0– 4) configurations of Li-like ions with Z=5–30 are calculated on the basis of the perturbation theory in 1/Z (the MZ code). The relativistic corrections are taken into account in terms of the Breit operator. The asymptotic behavior of the energy matrix of the 1s2lnl' states is studied as a function of n. The calculation is compared with the available theoretical and experimental data on the energies of both radiative and Auger transitions, the ions with Z = 6, 7, 8, 16, 17, and 18 in the 1s2lnl 'LSJ states with n = 2–7 being considered.
