摘要：

The beta-decay branching ratio of the GT transition in Na-21 to the first excited state in Ne-21 has been measured. The value obtained of 4.93(20)% is in agreement with the most recent measurement and with the value adopted so far. This confirms that the branching ratio is not the source of discrepancy in a previous measurement of beta-nu correlation coefficient which exhibited a 3 sigma difference with respect to the Standard Model prediction.
