[en] Gluon exchange corrections to non-leptonic decays are estimated in the non-relativistic quark model. These corrections to the dominant contribution, which arises from quark-quark scattering through Wsup(+-) exchange previously considered, are rather important and in the right direction. Within the framework of the current-current picture with (V-A) charged currents, not only the ΔI equal to 1/2 rule follows for the matrix elements Bsub(s)|Hsub(W)sup(pc)|Bsub(r) in our approach, but also the scale comes out to be right so as to compensate the Cabibbo suppression factor sinthetasub(c). The D/F ratio for the above matrix elements comes out to be -0,8, which can fit both p-wave and s-wave amplitudes
