摘要
采用光学模型系统地计算了高能α粒子的非卢瑟福散射截面．给出了与卢瑟福散射偏离度为4%和6%时的起始偏离以量随靶核电荷数Z的变化规律．计算结果与实验值有很好的符合。
In this paper,non-Rutherford cross sections for high energy alpha particle are calculated systematically by using a method of optical-model. The dependence of the projectile energy Enr,at which the scattering cross sction begins to deviate by 4% and 6% from its Rutherford value,on the nuclear charge Z is given. The calculated results agree well with the experimental values.
