$Q_{\text{EC}}$-value determination for ${}^{21}$Na${\to }^{21}$Ne and ${}^{23}$Mg${\to }^{23}$Na mirror-nuclei decays using high-precision mass spectrometry with ISOLTRAP at ISOLDE/CERN

Jonas Karthein, Dinko Atanasov, Klaus Blaum +14

We report on high-precision $Q_{\text{EC}}$ values of the ${}^{21}$Na${\to }^{21}$Ne and ${}^{23}$Mg${\to }^{23}$Na mirror $\beta$-transitions from mass measurements with ISOLT…
