Half-lives and branching ratios of some T=12 nuclei
Abstract
Precision half-life measurements and branching ratio determinations have been carried out for some T=12 mirror nuclei. The following results have been obtained for the half-life and for the branching ratios: 13N (597.9 +/- 0.6 s), 15O (122.23 +/- 0.23 s), 17F (64.31 +/- 0.09 s), 21Na [(95.8 +/- 0.2)%], 23Mg [11.317 +/- 0.011 s, (92.2 +/- 0.2)%], 25Al [(99.16 +/- 0.04)%], 27Si [(99.812 +/- 0.010)%], 29P [(98.11 +/- 0.30)%], 31S [2.543 +/- 0.008 s, (98.89 +/- 0.20)%], 33Cl (2.507 +/- 0.008 s), 35Ar [1.774 +/- 0.003 s, (98.0 +/- 0.2)%], 37K [1.223 +/- 0.008 s, (97.8 +/- 0.2)%], 39Ca (0.8594 +/- 0.0016 s, >99.72%). RADIOACTIVITY 13N, 15O, 17F, 21Na, 23Mg, 25Al, 27Si, 31S, 33Cl, 35Ar, 37K, 39Ca; measured T=12, branching ratios.
