Résumé :

We made a short review of previous investigations of lines of short-lived radioactive elements in the spectrum of Przybylski's star (HD101065) and show that the best atmosphere model available today should be significantly improved. The synthetic spectra in the vicinities of lines of neutral and ionized technetium are calculated. Comparison of these spectra with high resolution VLT and IUE spectra permits to discuss the possibility of existence of technetium in the atmosphere of Przybylski's star. © Copyright owned by the author(s).
