| Abstract: | 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. |
