摘　　要：用自己编写的STARF程序,系统地研究了低能高电荷态离子uq+(q=10-40)在Al(111)晶面上掠射时,反射系数、反射离子的角分布等对于离子入射角、电荷态和能量的依赖关系;并探讨了高电荷态离子在金属表面产生沟道效应的条件。Using STARF code developed by ourselves, the scattering of Uq+(q=10-40) from Al(111) surface under grazing angle were simulated. In our simulation, the dependence of the reflection coefficient and the reflection angle distribution on incidence angle, charge state and kinetic energy of the projectile were systematically studied. In the present work, our simulation results were also compared with results in references and found in good agreement with them.
