ONE BOSON EXCHANGE N-N,N-Δ AND Δ-Δ INTERACTION FROM QUARK POTENTIAL MODEL

The equivalent one-boson-exchange potentials of the N-N, N-Δ and Δ-Δ interaction were calculated rigorously in momentum space with the vertex functions derived from quark-pair-creation model.The results of the N-N interaction were compared with those calculated approximately in coordinate space and the conventional one-boson-exchange potentials. A11 of the results indicate that they have very similar behaviour for the medium- and Long-range parts.
