The L X-ray spectra of Ta, Au and Th induced by 0.6-4 MeV/nucleon Kr beams have been studied by means of a LiF (1 0 0)-equipped crystal spectrometer having an overall resolution of 30 eV at 8.146 keV. The mean energy shifts of the main L lines were measured and electron vacancy configurations deduced. At the highest beam energies L diagram lines have been observed and attributed to the internal conversion of transition energies between nuclear Coulomb excited levels. From the intensities of the main L lines, thick target yields and X-ray production cross sections are deduced. (C) 1998 Elsevier Science B.V.
