本文讨论了低密度（~ 1013 cm-3）和高密度（~ 1020 cm-3）托卡马克和激光等离子体中与PdI到CuI等电子的稀土离子的线发射和未分辨跃迁阵发射。在TEXT托卡马克等离子体中激发了镨、铕、钆、镝和镱的光谱，并通过光度校准的时间分辨多光谱掠入射摄谱仪在50-200 A范围内记录。用钕玻璃激光束聚焦固体靶，在同一光谱范围内将镨、钐、钆、镝和镱的光谱记录在照相底片上。分析讨论了等离子体的主要参数、电子温度和密度与稀土软X射线发射的关系。
A discussion of the line and unresolved transition arrays emission of rare earths ions isoelectronic with PdI to CuI emitted from low (~ 1013 cm−3) and high (~ 1020 cm−3) density tokamak and laser produced plasmas is presented. The spectra of prasaeodymium, europium, gadolinium, dysprosium and ytterbium have been excited in the TEXT tokamak plasma and recorded in the 50-200 A range by means of a photometrically calibrated, time-resolving multispectral grazing incidence spectrograph. The prasaeodymium, samarium, gadolinium, dysprosium and ytterbium spectra obtained by focussing an Nd-glass laser beam on solid targets were recorded in the same spectral range on photographic plates. The relationship between the main plasma parameters, electron temperature and density, and the soft X-ray emission of rare earths is analyzed and discussed.
