Direct decay-energy measurement as a route to the neutrino mass
A high-precision measurement of the$^{131}$Cs→$^{131}$Xe ground-to-ground-state electron-capture Q$_{EC}$-value was performed using the ISOLTRAP mass spectrometer at ISOLDE/CERN. The novel PI-ICR technique allowed to reach a relative mass precision δm/m of 1.4 ⋅ 10$^{− 9}$. A mass resolving power m/...
