X-ray spectra of highly ionized atoms (Tm to Pt) emitted from Laser produced plasma are characterized by the simple structure given by resonant transitions of the Nil-like ions, accompanied by the more complex pattern of satellite transitions emitted by ions in the neighbouring states of ionization. An analysis of these structures has been given recently for the satellites of the 3d10 − 3d94p[l] and of the 3p63dl0 − 3p53d104s, 4d[2] transitions of the Nil-like inns. However, most of the radiation emitted in this spectral range [4–10Å] concentrate in a wide, rather structureless satellite feature in the long wavelength side of the 3d10 −3d94f Ni-I like transition, on which some lines are superimposed. Line identification has been achieved successfully with the methods of [1], [2] and will be published separately. In this communication, we deal only with the pseudocontinuum.
