A quark compound bag model has been constructed to describe NN s-wave scattering up to 1 GeV. The model contains a vertex interaction H/sub D//sub bold-arrow-left-right//sub NN/ for describing the excitation of a confined six-quark bag state, and a meson-exchange interaction obtained from modifying the phenomenological core of the Paris potential. Explicit formalisms and numerical results are presented to reveal the role of the bag excitation mechanism in determining the relative wave function and the P and S matrices of NN scattering. We explore the merit as well as the shortcomings of the quark compound bag model developed by the Institute of Theoretical and Experimental Physics group. It is shown that the parameters of the vertex interaction H/sub D//sub bold-arrow-left-right//sub NN/ can be more rigorously determined from the data if the concept of the chiral/cloudy bag model is used to justify the presence of the background meson-exchange interaction inside bag excitation region. The application of the model to the study of quark degrees of freedom in nuclei is discussed.
