Abstract
High-resolution triple- coincidence data were used to reconstruct the decay of the excited states in C at 7.65 MeV () and 9.64 MeV . These data are consistent with the -particle decay of both levels proceeding exclusively through Be. In the first of these cases, the Hoyle state, an upper limit of 0.45% (at the 99.75% confidence level) is set for a component producing three nearly equal-energy particles.
