Ar中抖动现象观察

Observation of Shake-Up in Ar

本文叙述了利用准分于紫外激光打靶产生的软Ｘ射线激励（ＬＰＸ）所观察到的Ａｒ中抖动（Ｓｈａｋｅ－ｕｐ）现象．对Ａｒ＋３ｐ４４ｐ与下能态跃迁产生的６８条谱线进行了识别，标定，除两条谱线没观察到外，其余所有可能产生的跃迁谱线都已被观察到．

The phenomenon of Shake-up in Ar excited by laser produced plasma (LPX) by using a beam of UV excimer laser injected onto a Ta target is described in this paper. The 68 transition lines originated from the Ar+ 3p4p are identified among which 66 possible lines are observed in the experiments.
