A model for the high-Tc superconductors which takes into account two O's and one Cu atoms with one orbital in each atom is set up. The dynamically screened hole-hole interaction is deduced from the random-phase approximation. We calculate the pair potential, the spectral function and the density of states of the interacting system, as a function of the quasimomentum of the bubble polarization. © 1994.
