The first-order optical potential for elastic nucleus-nucleus scattering is derived, taking into account binding and Fermi motion effects through an optimal approximation. The resulting potential is expressed as a product of the projectile elastic form factor times the nucleon-nucleus elastic amplitude (rather than the nucleon-nucleus potential as in the folding model). The effective energy in this amplitude rises with angle and agrees with the usual choice of the folding model for forward angles. The form of the spin-orbit nucleus-nucleus potential for projectiles with spin is discussed as well.
