Comparison of negatron decays with positron decays is made for allowed GT type transitions from the ground 1 + states in odd-odd nuclei to the ground 0 + and first 2 + states in even-even nuclei. The f t values of negatron decays are systematically larger than those of positron decays by factors 2∼12. The difference between log f t values of negatron decays and positron decays is discussed in terms of the theoretical effective coupling constant g eff and the pairing model.
