利用扭曲波波恩近似方法及AUTOSTRUCTURE(AS)程序,快速精确地计算了类氖Ar8+离子2s22p6、2s22p53s、2s22p53p、2s22p53d、2s2p63s、2s2p63p和2s2p63d组态的能级以及当电子碰撞能量为75.0、125.0、175.0、250.0(Ry)时,从j能态到i能态的碰撞强度.并且与已有的研究成果进行了对比.结果表明,采用扭曲波波恩近似并结合AUTOSTRUCTURE(AS)程序的研究方法,可以成为研究原子或离子碰撞强度的有效途径.

By means of a new rapid and accurate fully relativistic distorted wave born approximation and AUTO- STRUCTURE （AS） program , the collision strengths of some highly charged ions are calculated. The 2s^22p^6,2s^22p^53s、2s^22p^53p、2s^22p^53d、2s^2p^63s、2s^2p^63d configurations of Ne - like Ar^8＋ ion are mainly studled. Their energy levels and collision strengths from j to i states are calculated when the collision energies are 75.0,125.0,175.0 and 250. 0 （Ry）. The calculated results are compared with the experimental data. It is found that the fully relativistic distorted wave born approximation and AUTOSTRUCTURE （AS） program provide the good and effective way for studying the electron - impact excitations of complex atoms or ions.
