β -decay measurements of 12B with Gammasphere
The β-decay branching ratio of 12B to the Hoyle state in 12C was measured by detection of γ rays. 12B nuclei were produced via the 11B(d,p)12B reaction in inverse kinematics on a TiD2 target. The present results corroborate those obtained recently for the β branch by implantation. The value from both experiments is inconsistent with that accepted in the literature
