Dravins, Nordlund and coworkers (ref. 1, 2, 3) discussed the importance of the granulation in determining the C-shape of solar lines of Fe I and Fe II ions. Iron is a suitable atomic species to diagnose photospheric motions, since it has negligible asymmetries due to isotope composition and to pressure shifts and no hyperfine structure splitting. Marmolino, Roberti, Severino and coworkers studied the effects produced by photospheric oscillations (5 - min and short period acoustic waves) on the resonance line of KI at 7699 A (ref. 4, 5, 6). To extend this study to iron lines, in this paper we show the synthesis of the Fe II 6516 line in the presence of granulation and 65 - min oscillation.
