The extended quark model study of the NN interaction, in which the (q~) excitations inherent in the quark-gluon interaction are explicitly incorporated into the model space, is completed with the inclusion of the (qf=l)(q?=l) excitations generated by RPA-type terms of the color Breit interaction. The new coupling kernels connecting the dominant (3q)-(3q) components of the NN system to the (3q)-(3q)(q~)(q~l) components lead to potentials with the characteristics of conventional o and ~ meson

The full model is subjected to a quantitative test through a solution of the RGM equations in a coupled channel formalism. With one improvement of the model, to yield an N~ tensor force with OPEP strength and long-range characteristics, this model leads to a prediction of the low-energy NN scattering data and deuteron bound state characteristics which is in semiquantitative agreement
