Fermi Beta Decay, A>40: The Half-lives of V46, Mn50, and Co54 Academic Article uri icon


  • Half-lives for V46, Mn50, and Co54 have been measured to be 423.4 2.0, 284.0 0.4, and 193.4 0.4 msec, respectively. The Mn50 result is significantly different from the previously accepted value, and brings the ft value for the decay of Mn50 into agreement with all other accurately known 0+0+ superallowed decays. These new data are in complete agreement with the predictions of conserved vector current theory. 1974 The American Physical Society.
