Abstract

A high-precision half-life measurement for the superallowed Fermi β+ emitter ²²Mg was performed at the TRIUMF-ISAC facility using a 4π proportional gas counter. The result of T_1/2=3.87400±0.00079 s is a factor of 3 more precise than the previously adopted world average and resolves a discrepancy between the two previously published ²²Mg half-life measurements.
