Abstract

We report the first direct measurement of the transition energy QEC of the Na21 mixed Fermi-Gamow-Teller decay. This is the first of the T=1/2 mirror nuclei decays used for the determination of Vud to be measured with Penning trap mass spectrometry. In addition, the P29 mass was measured directly for the first time and used along with the mass of its daughter, Si29, for the independent QEC determination of this decay. The obtained QECNa21=3547.11(9) keV and MEP29=-16953.15(47) keV significantly improve the latest published values and reduce the contribution of the QEC uncertainty on Ftmirror to the same order as the theoretical corrections.
