Erratum: QEC -value determination for Na21→Ne21 and Mg23→Na23 mirror-nuclei decays using high-precision mass spectrometry with ISOLTRAP at the CERN ISOLDE facility [Phys. Rev. C 100 , 015502 (2019)]
Physical Review C
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
... relevant quantities. Equation (4) in the original publication now reads with the literature mass for the reference atom m ref,lit , the electron mass m e , 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 , 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  in comparison with the ones published by Low-Energy Beam and Ion Trap (LEBIT) for 21 Na  and by TRIUMF Ion Trap for Atomic and Nuclear Science (TITAN) for 23 Mg .
