Abstract

The branching ratio of the isomeric γ decay of 24mAl has been measured to be 69.6(7)% which is much smaller than the previously accepted value of 82.5(30)%. As a result, the branching ratio to the 24Mg ground state increases up to 24.1(7)% assuming that the other β-decay branching ratios are the previously accepted values. The half-life of 24mAl was also precisely determined to be 130.9(13) ms. The B(GT) value from the ground state of 24Mg to the 24mAl of 0.0577(16) deduced from the β decay is now in good agreement with that deduced from charge-exchange reactions.
