Abstract: 
We report Dirac-Fock calculations of transition energies for kaonic neon (KNe). For the most in- tense line, the 7–6 transition, the calculated energy is 9450.28 eV, which includes a bound-state QED (BSQED) contribution of 12.66 eV. This is in excellent agreement with the recent SIDDHARTHA-2 measurement at DAΦNE of 9450.23±0.37 (stat.)±1.50 (syst.) eV. With the QED shift far exceeding experimental uncertainty, these results establish kaonic atoms as powerful platforms for precision tests of BSQED in intermediate-Z systems.
