The $\beta-\gamma$ decay of $^{21}$Na
A new and independent determination of the Gamow-Teller branching ratio in the $\beta$-decay of $^{21}$Na is reported. The value obtained of 5.13 $\pm$ 0.43 % is in agreement with the currently adopted value and the most recent measurement. In contrast to previous experiments, the present method was...

| Sumario: | A new and independent determination of the Gamow-Teller branching ratio in the $\beta$-decay of $^{21}$Na is reported. The value obtained of 5.13 $\pm$ 0.43 % is in agreement with the currently adopted value and the most recent measurement. In contrast to previous experiments, the present method was based on the counting of the parent $^{21}$Na ions and the resulting 351 keV $\gamma$-rays without coincident $\beta$-particle detection. |
