Detailed measurements of α-particle emission double differential cross section for beryllium and carbon with 14-MeV incident neutrons were carried out. In order to identify contributing reaction channels to the 9Be(n,2n + 2α) and 12C(n,n' + 3α) reactions, we attempted to reproduce energy distributions of emitted particles by Monte Carlo calculations according to reaction kinematics of a lot of channels which contribute to the reactions. As for the 9Be(n,2n + 2α) reaction, a contribution of the 9Be(n,α)6He* channels and the simultaneous breakup channel was suggested to account for the energy and angular distribution of emitted α-particles and neutrons. As for the 12C(n,n' + 3α) reaction, the 12C(n,α)9Be* channels were largely contributed and well reproduced the experimental data.
