N2 - We report on a measurement of the 44Ti half-life aimed at lowering existing systematic uncertainties in this value, which is important to astrophysics. The half-life was measured by following the decay of 44Ti relative to 60Co for about 5 yr and the measurements were performed independently in three laboratories—Argonne, Jerusalem, and Torino. We suggest to combine our result, 59.0±0.6 yr, with the one from the accompanying Letter by Görres et al., 60.3±1.3 yr, to obtain a current “best value” for the half-life of 44Ti of 59.2±0.6 yr (1σ error).
