中文摘要：
采用全相对论扭曲波方法,系统地计算了类铍N^3＋和O^4＋离子从基态到2s2p和2p2的各激发态以及从亚稳态到2p2各激发态的电子碰撞激发截面,详细地讨论了靶态的关联效应对激发截面的影响.结果表明：对于2s-2p的单电子激发,在低能碰撞时,靶态的电子关联效应起非常重要的作用,且使得激发截面降低;而高能碰撞时,靶态波函数的描述对连续态波函数的影响比较小,对激发截面影响也比较小.对于2s^2-2p^2的双电子激发,其中基态2s^2^1S0到J=0的2p^2^3P0,^1S0的激发截面较大,其主要原因是末离子态波函数与基组态波函数的混合,但是其他几个激发的激发截面较小.
英文摘要：
By using a fully relativistic distorted-wave method,the electron impact excitation cross sections of Be-like N^3＋ and O^4＋ ions from the ground state 2s^21S to 2s2p ^1,3P,2p^2 3P,1^D and ^1S 2s2p and from the metastable 2s2p ^3P to 2p^2 3P have been calculated systematically.Meanwhile,the correlation effects of target states are also discussed.For the low energy collisions the correlation effects play a very important role,and accurate target wavefunctions are needed,but for the high energy collisions,the more correlation effects are not so important.For two-electron excitations,the configuration interactions are very important and the excitations from ground state to the 2p^2 3P0 and 1^S0 have larger cross sections than the other tow electron excitations.
