高离化氩原子光谱的实验和理论研究
-
摘要: 利用兰州重离子加速器将从ECR离子源射出的Ar4+离子加速、剥离，获得了能量为93.8MeV的 Ar8+离子束流，测量了这些束流通过碳箔后各种离子的发射光谱。根据用全相对论多组态自洽场方法计算出的有关原子数据, 对这些光谱进行了识别和分析。Abstract: Ar4+ ions from ECR ion source are speed up a nd peel off with Lanzhou Heavy Ions Accelerator, so Ar8＋ ions with energy 93.8 MeV are obtained. According to atom data calculated by the expanded full r elativistic multiconfiguration Dirac-Fock(GRASP) code, we have distinguished and analysed those spectrams.
