Abstract

The half-life of 14O, a superallowed Fermi emitter, has been determined via simultaneous and counting experiments at TRIUMF's Isotope Separator and Accelerator facility. Following the implantation of 14O samples at the center of the 8 spectrometer, a counting measurement was performed by detecting the 2313 keV rays emitted from the first excited state of the daughter 14N using 20 high-purity germanium (HPGe) detectors. A simultaneous counting experiment was performed using a fast plastic scintillator positioned directly behind the implantation site. The results, T1=2( ) = 70:632 0:094 s and T1=2( ) = 70:610 0:030 s, are consistent with one another and, together with eight previous measurements, establish a new average for the 14O half-life of T1=2 = 70:619 0:011 s with a reduced 2 of 0.99.
