本文报告了对等离子体中离子谱线的电子碰撞展宽和线移的相对论量子力学计算.具体地,首先利用相对论原子结构程序GRASP 计算出辐射体(靶离子)的原子结构参数,然后依据DACR 来构造N+1 电子碰撞体系,得到体系的反应矩阵和相关的对称信息,并以此计算出散射矩阵,从而实现电子碰撞展宽的数值计算.最后,一些数值计算结果:1)单态和三重态2s3s←2s3p 跃迁中四种类铍离子(N Ⅳ,O Ⅴ,F Ⅵ 和Ne Ⅶ)的相对论电子碰撞展宽计算结果.仔细比较发现,我们的结果与已有的实验结果相当一致,也好于其它理论计算的结果(B.Duan et al,A & A(即Astronomy & Astrophysics 下同),547,A4(2012)).2)He Ⅱ 离子谱线的电子碰撞展宽和位移的相对论量子力学计算.
