从德克萨斯托卡马克(TEXT)等离子体记录的高度电离的Pr和Dy的光谱已经在50-250-A范围内进行了分析。光谱包含在100A以下的高强度连续谱带和高于该波长的明亮的单条谱线。已经确定了高度电离的Pr和Dy的谱线。在中心电子温度为1keV的托卡马克等离子体中达到的最高电离态是类铜 类Pr xxxi。用一种新的理论方法解释了这些带的组成，这种新的理论方法是用来处理大型未分辨跃迁阵列的。将连续谱的亮度与在相同波长范围内发射的强谱线的亮度进行了比较。
Spectra of highly ionized praseodymium and dysprosium recorded from the Texas tokamak (TEXT) plasma have been analyzed in the 50–250‐A range. The spectra contain high‐intensity continuum bands in the region below 100 A and bright individual lines above this wavelength. Lines of highly ionized praseodymium and dysprosium have been identified. The highest ionization state reached in the 1‐keV central electron temperature tokamak plasma was Cu i‐like Pr xxxi. The composition of the bands is explained in terms of a new theoretical approach developed to treat large unresolved transition arrays. The brightness of the continuum is compared with that of intense spectral lines emitted in the same wavelength range.
