          Abstract

          We have measured the half-life of \(^{14}\)O, a superallowed \((0^{+} \to 0^{+})\) \(\beta\) decay isotope. The \(^{14}\)O was produced by the \(^{12}\)C(\(^{3}\)He,n)\(^{14}\)O reaction using a carbon aerogel target. A low-energy ion beam of \(^{14}\)O was mass separated and implanted in a thin beryllium foil. The beta particles were counted with plastic scintillator detectors. We find \(t_{1/2} = 70.696\pm 0.052\) s. This result is \(1.5\sigma\) higher than an average value from six earlier experiments, but agrees more closely with the most recent previous measurement.
