High-precision measurement of a low Q value for allowed β-decay of ¹³¹I related to neutrino mass determination

RADIOACTIVITY ¹³¹I(β^-) [from U(p, X), E=30 MeV]; measured cyclotron frequency ratios; deduced Q-value, partial T_1/2 for the transition. Comparison with the Atomic Mass Evaluation 2020, theoretical calculations. The double Penning trap mass spectrometer JYFLTRAP at the IGISOL facility, the K-130 cyclotron.
