Abstract: The Schr\- odinger picture of the Dirac quantum mechanics is defined incharts with spatially flat Robertson-Walker metrics and Cartesian coordinates.The main observables of this picture are identified, including the interactingpart of the Hamiltonian operator produced by the minimal coupling with thegravitational field. It is shown that in this approach new Dirac quantum modeson de Sitter spacetimes may be found analytically solving the Dirac equation.
