Accurate Q value for the ⁷⁴Se double-electron-capture decay

ATOMIC MASSES ⁷⁴Ge, ⁷⁴Se; measured masses using JYFLTRAP penning trap; deduced Q-value for neutrino-less 2EC decay.

RADIOACTIVITY ⁷⁴Se(2EC); deduced Q-value for neutrino-less 2EC decay from atomic mass measurements; calculated T_1/2 and nuclear matrix elements using QRPA wave functions in a multiple-commutator model.
