## Contribution

It provides the first comprehensive QED-based g-factor calculations for this state across a range of Z, improving accuracy over previous models.

## Key findings

- Calculated g-factors for Z=10 to 20 ions.
- Quantified interelectronic and QED corrections.
- Compared results with previous data.

## Abstract

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.
