N2 - 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 Å 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.
