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.
