本文介绍了用电子束离子阱（EBIT）获得的类铥钨和金的极紫外和可见光谱。虽然从几个电荷状态的贡献涉及在光谱中，分配给所观察到的线的离子的电荷状态是明确确定的飞行时间分析的离子在同一时间进行的光谱测量。实验结果与碰撞辐射模型计算以及以前的实验和理论研究进行了比较。
We present extreme ultraviolet and visible spectra of promethiumlike tungsten and gold obtained with an electron beam ion trap (EBIT). Although the contributions from a few charge states are involved in the spectra, the charge state of the ion assigned to the observed lines is definitely identified by the time-of-flight analysis of the ions performed at the same time with the spectroscopic measurements. Experimental results are compared with collisional-radiative model calculations as well as previous experimental and theoretical studies.
