摘　　要：利用R矩阵方法计算了电子与He+离子碰撞的1s-2s和1s-2p跃迁的碰撞强度,结果表明包括10个靶态的计算可以得到精确的类氢离子的n=1→n=2各能级跃迁的碰撞强度,并首次利用R矩阵方法计算了电子与Li2+离子碰撞的1s-2s和1s-2p跃迁的碰撞强度。Electron collision strengths for 1s-2s and 1s-2p transitions of He^+ ion have been calculated using closed-coupling R-matrix method. Our results shows that calculations should include, at least, ten target states, which can give accurate data for electron collision strengths for excitation of n=2 states from ground state of hydrogen-like ions. We also calculated the collision strengths for 1s-2s and 1s-2p transitions of Li^(2+) ion for the first time.
