The cross sections for the 12C(γ,α)8Be→ 3α reaction have been successfully measured using exclusive coincidence between three α particles, minimizing Compton background. Sequential breakup kinematics are evident, and the cross sections are presented as locally averaged histogram values. Theoretical Fresco CDCC-CRC calculations reproduce the experimental data, showing that the process involves electromagnetic coupling to both 8Be0+ and 8Be2+ states. This study confirms that the 12C(γ,α)8Be→ 3α reaction proceeds via a sequential mechanism, crucial for understanding its significance in radiotherapy dosimetry.
