用上海高温超导电子束离子阱研究了类铥钨（W13+）的可见跃迁。基态（4f135s22F）精细结构能级间的M1跃迁波长为549.95± 0.06nm。还发现了来自W 13+的其他7条谱线，其中5条属于第一激发组态（4f 12 5s 2 5p）内的跃迁。这些线被分配的相对论组态相互作用计算和碰撞辐射模型预测的相对线强度的帮助下。
Visible transitions of promethium-like tungsten (W 13+) were studied using the Shanghai high temperature superconducting electron beam ion trap. The M1 transition between the ground state (4f 13 5s 2 2 F) fine structure levels was measured to be at 549.95±0.06 nm. Seven other lines from W 13+ were also found and five of them were classified as belonging to transitions within the first excited configuration (4f 12 5s 2 5p). These lines were assigned with the help of relativistic configuration interaction calculations and collisional-radiative model predictions of the relative line intensities.
