摘要：

The half-life of the T=(3/2 nucleus O13 has been remeasured to be T1/2=(8.550.05) ms by observing a time spectrum of delayed protons. This value is appreciably smaller than previously reported. Branching ratios of the transitions to the ground and excited states of N13 have been obtained from the proton energy spectrum and the proton-to intensity ratio. Mirror asymmetry in the ft value deduced for the ground-state transition is found to be consistent with the theoretical estimate which takes account of nuclear asymmetry due to the Coulomb interaction. © 1990 The American Physical Society.
