| contents | The cross sections for the $^{12}\mathrm{C}(γ,α)^{8}\mathrm{Be}\rightarrow 3α$ 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 \textsc{Fresco} CDCC-CRC calculations reproduce the experimental data, showing that the process involves electromagnetic coupling to both $^{8}\mathrm{Be}^{0^+}$ and $^{8}\mathrm{Be}^{2^+}$ states. This study confirms that the $^{12}\mathrm{C}(γ,α)^{8}\mathrm{Be}\rightarrow 3α$ reaction proceeds via a sequential mechanism, crucial for understanding its significance in radiotherapy dosimetry. |
