Using one high dispersion high quality spectrum of Vega (HR7001, A0V) obtained with the echelle spectrograph SOPHIE at Observatoire de Haute Provence, we have measured the centroids of 149 flat-bottomed lines. The model atmosphere and spectrum synthesis modeling of the spectrum of Vega allows us to provide identifications for all these lines. Most of these lines are due to C I, O I, Mg I, Al I, Ca I, Sc II,Ti II, Cr I, Cr II, Mn I, Fe I, Fe II, Sr II, Ba II, the large majority being due to neutral species, in particular Fe I.
