Query: Independent measurement of the Hoyle state $\beta$ feeding from 12B
  using Gammasphere   Using an array of high-purity Compton-suppressed germanium detectors, we
performed an independent measurement of the $\beta$-decay branching ratio from
$^{12}\mathrm{B}$ to the second-excited (Hoyle) state in $^{12}\mathrm{C}$. Our
result is $0.64(11)\%$, which is a factor $\sim 2$ smaller than the previously
established literature value, but is in agreement with another recent
measurement. This could indicate that the Hoyle state is more clustered than
previously believed. The angular correlation of the Hoyle state $\gamma$
cascade has also been measured for the first time. It is consistent with
theoretical predictions.
