通过将这些元素注入TEXT托卡马克的等离子体，观察到了高度电离的Er、Yb、Hf、W和Pt的光谱。通过与观察到的负计算跃迁能图的比较，确定了Pd I等电子序列中4d10-4d94f跃迁阵列的共振线。这些曲线图是基于之前通过Ho21+获知的数据。它们被拟合到低阶多项式中，从而可以准确地预测Bi37+的波长。此外，还观察到类锌Er38+和Hf42+的共振线。
Spectra of highly ionized Er, Yb, Hf, W, and Pt were observed by injecting these elements into the plasma of the TEXT tokamak. Resonance lines of the 4d10–4d94f transition array in the Pd i isoelectronic sequence were identified by comparison with plots of observed-minus-calculated transition energies. These plots were based on data previously known through Ho21+. They were fitted to low-order polynomials that permitted accurate predictions of wavelengths to Bi37+. In addition, resonance lines of Zn-like Er38+ and Hf42+ were observed.
