Abstract
The reaction B + p has been used to populate the $ (J^{\pi},T) = (2^{+},1)$ state at an excitation energy of 16.11 MeV in C, and the breakup of the state into three $\alpha$ -particles has been studied in complete kinematics. A two-step breakup model which includes interference effects is found to provide the most accurate description of the experimental data. The branching ratio to the ground state of Be is determined to be 5.1(5)% in agreement with previous findings, but more precise by a factor of two, while the decay to the first excited state in Be is found to be dominated by d-wave emission.
