Scientific paper

Several observations of some Ap stars have been made at the ESO, Nordic and Crimean telescopes in 1996. Interesting results have been found for the roAp star HD 83368 = HR 3831 in the Li spectral region. These have shown the presence of two almost diametrically opposed spots of Li or of the element responsible for the ``Li'' blend, which cause strong variations in the profile and position of the Li blend at 6708 Angstroms. Based on observations collected at the European Southern Observatory, La Silla, Chile
