✦ Synopsis


The g factor of Li-like ions in the range Z = 6-92 is evaluated. The interelectronic-interaction corrections of order 1/Z 2 and higher are taken into account by the configuration-interaction Dirac-Fock method. This result is combined with the 1/Z term derived within a rigorous QED approach. The one-electron QED correction of first order in a is obtained by employing our recent results for the self-energy term and by evaluating the vacuum-polarization term. The screening of the QED effects is calculated to the leading orders in aZ and 1/Z. A significant improvement of the theoretical accuracy of the g-factor values is achieved.

## Abstract The energies of the five lowest ^4^__S__ and ^4^__P__^0^ states for three‐electron ions for 3β©½__Z__β©½10 have been calculated by the Hylleraas method. The largest basis set used contained 97 terms with odd as well as even powers of __r__~__ij__~. The change of scale __r__β€² = __Zr__ was ap
