在利弗莫尔电子束离子阱（EBIT-I）上用平场光栅谱仪和NASA/戈达德航天飞行中心X射线微热计测量了Ni XIX中3 → 2发射谱线的强度比。结果是一致的，与早期的测量Fe XVII和其他Ne离子在利弗莫尔和确认的问题，在原子模型的直接碰撞激发Ne类系统。
The intensity ratios between 3 → 2 emission lines in Ni XIX were measured on the Livermore electron beam ion trap (EBIT-I) with a flat-field grating spectrometer and the NASA/Goddard Space Flight Center X-ray microcalo-rimeter. The results are consistent with earlier measurements of Fe XVII and other Ne-like ions at Livermore and confirm the problems in the atomic modeling of the direct collisional excitation for Ne-like systems.
