In our original publication concerning the Q-value determination for the 21 Na → 21 Ne and 23 Mg → 23 Na mirror-nuclei decays, the ionization energy was not included. The Q values of the presented β decays, hence, change by 17 eV in the case of 21 Na → 21 Ne and 3 eV in the case of 23 Mg → 23 Na. The essence of the paper, namely, the calculated Ft values and the resulting V ud element of the CKM-quark-mixing matrix are not affected due to dominating uncertainties in the other relevant

Equation (4) in the original publication now reads with the literature mass for the reference atom m ref,lit , the electron mass m e [1], the speed of light c, and the ionization energies for the reference atom and atom of interest, E i,ref and E i,IOI respectively. As a result, Table I is modified to: TABLE I. Summary for 21 Na + and 23 Mg + showing the number of Ramsey-type spectra taken, the estimated production yield at ISOLDE, the half-lives [2], the reference ion for cyclotron frequency ratio determination, the measured cyclotron frequency ratio r, and the measured Q EC values using ionization energies from the National Institute of Standards and Technology [3] in comparison with the ones published by Low-Energy Beam and Ion Trap (LEBIT) for 21 Na [5] and by TRIUMF Ion Trap for Atomic and Nuclear Science (TITAN) for 23 Mg [4].
