Phys. Rev. C 71, 044309 (2005) [13 pages]High precision measurements of 26Na β− decayReceived 22 November 2004; published 21 April 2005 High-precision measurements of the half-life and β-branching ratios for the β− decay of 26Na to 26Mg have been measured in β-counting and γ-decay experiments, respectively. A 4π proportional counter and fast tape transport system were employed for the half-life measurement, whereas the γ rays emitted by the daughter nucleus 26Mg were detected with the 8π γ-ray spectrometer, both located at TRIUMF's isotope separator and accelerator radioactive beam facility. The half-life of 26Na was determined to be T1/2=1.07128±0.00013±0.00021 s, where the first error is statistical and the second systematic. The logft values derived from these experiments are compared with theoretical values from a full sd-shell model calculation. © 2005 The American Physical Society URL:
