$g$ factor of the $[(1s{)}^2(2s{)}^{2}2p]{}^2{P}_{3\mathrm{/}2}$ state of middle-$Z$ boronlike ions

Theoretical \emph{g}-factor calculations for the first excited \exst state of boronlike ions in the range $Z$=10–20 are presented and compared to the previously published values. The first-order interelectronic-interaction contribution is evaluated within the rigorous QED approach in the effective screening potential. The second-order contribution is considered within the Breit approximation. The QED and nuclear recoil corrections are also taken into account.
