    • Precise half-life measurement of the superallowed beta(+) emitter (38)K(m) 
      Ball, G. C.; Boisvert, G.; Bricault, P.; Churchman, R.; Dombsky, M.; Lindner, T.; Macdonald, J. A.; Vandervoort, E.; Bishop, S.; D'Auria, J. M.; Hardy, John C.; Iacob, V. E.; Leslie, J. R.; Mak, H. -B. (American Physical Society, 2010)
      The half-life of (38)K(m) has been measured to be 924.46(14) ms, a result that is a factor of two more precise than any of the five previous measurements of this quantity. The previous results are not consistent with one ...
    • Precise half-life measurements for the superallowed beta(+) emitters Ar-34 and Cl-34 
      Iacob, V. E.; Hardy, John C.; Brinkley, J. F.; Gagliardi, Carl A.; Mayes, V. E.; Nica, N.; Sanchez-Vega, M.; Tabacaru, G.; Trache, L.; Tribble, Robert E. (American Physical Society, 2006)
      To contribute meaningfully to any test of the unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the measured ft value of a superallowed 0(+)-> 0(+) beta(+) transition must be obtained to a precision of 0.1% or better. ...
