Abstract The branching ratios of the beta-decay of12B and12N to the 4.44 MeV state in12C were determined by (βγ-coincidences to be (1.182±0.019)% and (1.898±0.032)% of the total rate, resp. This givesft −=(1.407±0.023) · 105 s andft +=(1.406±0.024) · 105 s. For theft-asymmetryδ=(ft +/ft −)−1 the valueδ=−(1±14) · 10−3 was obtained. This is in contrast to other GT mirror transitions which show positiveδ of a few percent.
