摘要
实验测量了２９４ＭｅＶ２０Ｎｅ＋１２Ｃ反应中出射α粒子的单举能谱及角分布，用三源模型拟合了实验数据，大角度出射α粒子的实验结果表明了靶核碎裂（ｂｒｅａｋｕＰ）机制的存在．
Inclusive energy spectra and angutar distribution of α-particles have been measured in the reaction of 294MeV 20N bombardment of 12C target. Three sources fitting was Performed for the experimental data. The fact of α-particle emission at large angles indicates the process of target breakup.
