High precision measurements of Na-26 beta(-) decay Academic Article uri icon


  • High-precision measurements of the half-life and -branching ratios for the - decay of 26Na to 26Mg have been measured in -counting and -decay experiments, respectively. A 4 proportional counter and fast tape transport system were employed for the half-life measurement, whereas the rays emitted by the daughter nucleus 26Mg were detected with the 8 -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 log f t values derived from these experiments are compared with theoretical values from a full sd-shell model calculation. 2005 The American Physical Society.
