A new setup consisting of four 5” by 5” NaI scintillators and an array of particle detectors is being developed. Proton-gamma-gamma coincidences will be measured using the 12C(p, p′)12C reaction at 10.5 MeV energy. The new setup will be used for the measurement of the electromagnetic decay rate of the Hoyle state via two E2 transitions. We report the initial experimental results for singles gamma and gamma-proton coincidences through inelastic scattering of protons on a 12C target.
