Abstract：
The summed energy spectra and the angular correlation for two alpha particles from the ¹²C(α, 2α) ⁸Be reaction were measured.
The data show that the quasi-free scattering of incident alpha particle from the alpha cluster in ¹²C is probably the main mechanism of the reaction on 12C. The data are analyzed by means of PWIA. The probability of forming cluster is 0.07 which is close to the result obtained by James at high incident energy.
