Abstract: (Elsevier)
The β-decays of 23 Mg and 27 Si have been studied by observing the delayed γ-radiation. The following branches (and log ft values) have been found for 23 Mg (β + ) 23 Na : 0 keV , 0.914 ± 0.002 (3.67); 440 keV , 0.086 ± 0.002 (4.40); and 2391 keVa (6.9 ± 0.9) × 10 −5 (4.98); and for 27 Si (β + ) 27 Al : 0 keV , 0.9977 ± 0.0002 (3.61); 1014 keV , (4.9 ± 2.4) × 10 −5 (7.3); 2211 keV , (1.80 ± 0.13) × 10 −3 (4.68); 2734 keV , (1.55 ± 0.17) × 10 −4 (5.02); and 2981 keV , (2.59 ± 0.24) × 10 −4 (4.33) . The branches to the 2391 keV level from the 23 Mg decay and to the 2734 keV level from the 27 Si decay have not been previously reported. A comparison is made between the experimental results and the predictions of the many-particle shell model.
