High-precision proton angular distribution measurements of 12C (p, p') for the decay branching ratio of the Hoyle state

NUCLEAR REACTIONS 12C(p, p'), E=10.20-10.70 MeV from 14UD electrostatic accelerator at HIAF-ANU facility; measured E(p), I(p), p(θ), differential σ(θ, E) for the first 2+ and second 0+ (Hoyle) state using the Breakup Array for Light Nuclei (BALiN) array of wedge shaped segmented double-sided silicon detectors (DSSDs), configured as two ΔE-E telescopes; deduced total σ(E) for the population of the first 2+ and second 0+ (Hoyle) state in 12C, thick target yields.
