从12C原子核的α粒子结构观点出发,计算了共振区内能量为T p=200,400,600,700MeV,p-12C的2+(4.44MeV)和3-(9.64MeV)非弹性散射微分截面。其中将12C原子核跃迁形状因子分解成核内α粒子的跃迁形状因子和α粒子本身的形状因子的乘积。利用已知的原子核跃迁密度,得出12C原子核α粒子跃迁密度分布的解析式。理论结果与实验较好地符合。 From the point of view of the alpha particle structure of 12C nuclei, the differential cross-sections of 2+ (4.44MeV) and 3- (9.64MeV) inelastic scattering of p-12C with energy T p = 200, 400, 600 and 700 MeV in the resonance region were calculated. The 12C nucleus transition shape factor is decomposed into the product of the transition shape factor of the alpha particle and the shape factor of the alpha particle itself. Using the known nuclear transition density, the analytic formula of the transition density distribution of 12C atomic nuclei is derived. The theoretical result is in good agreement with the experiment.
