[en] The spectrum of xenon injected into the TFR tokamak plasma has been recorded in the range 10-90 A by means of a 2m grazing incidence spectrograph. Forty-four lines and unresolved transition arrays pertaining to multicharged xenon ions isoelectronic with Cu I, Ni I, Co I, Fe I, Mn I and Cr I have been identified by means of various theoretical methods. The 17 observed lines of the 3p⁶3d⁸ - 3p⁵3d⁹ transition array, have allowed the wavelengths of the magnetic dipole transitions occuring within the ground configuration 3d⁸ of Xe XXXIX to be predicted
