Résumé : | The L X-ray spectra of Ta, Au and Th induced by 0.6 to 4 MeV/nucleon (MeV/n) 84Kr ions have been studied by means of a LiF(100) equipped crystal spectrometer with an overall resolution of 30 eV at 8.146 keV. The mean energy shifts of the main lines have been measured with accuracies ranging from 5 eV for well separated lines, to 30 eV for poorly resolved lines. Mean energy shifts per M and N spectator electron vacancies were deduced and compared with predictions of different models. The mean number of these vacancies at the various beam energies were estimated. Diagram lines were also observed and assigned to the internal conversion of transition energies between nuclear Coulomb excited levels. In the case of the Lα lines of Ta and Au and at the lower beam energies (0.6 and 1.2 MeV/n) the full width at half maximum of these lines was used to deconvolute the shifted peaks in the individual corresponding satellite lines. © Springer-Verlag 1997. |
