摘要

We report on high-precision Q(EC) values of the Na-21 -> Ne-21 and Mg-23 -> Na-23 mirror beta transitions from mass measurements with ISOLTRAP at the CERN ISOLDE facility. A precision of delta m/m = 9 x 10(-1) and delta m/m = 1.5 x 10(-9) was reached for the masses of Na-21 and Mg-23, respectively. We reduce the uncertainty of the Q(EC) values by a factor of 5, making them the most precise experimental input data for the calculation of the corrected Ft value of these mixed Fermi and Gamow-Teller transitions. For the Na-21 -> Ne-21 Q(EC) value, a 2.3 sigma deviation from the literature Q(EC) value was found.
