Title: High-precision Q EC -value measurement of the superallowed β + emitter Mg 22 and an ab initio evaluation of the A = 22 isobaric triplet

The direct atomic mass difference between 22Mg and 22Na was measured using TRIUMF's Ion Trap for Atomic and Nuclear Science (TITAN) and was determined to be Q=4781.40(22) keV. This measurement represents the most precise single measurement of this quantity to date.
