Abstract
A study of nonrelativistic resonating group method quark exchange kernels shows that even large changes in the relative [6] and [42] space symmetry of the six-quark system do not make significant changes in the extreme short range parts of the NN interaction. The repulsive core heights of equivalent local potentials derived by the Wentzel-Kramers-Brillouin approximation from the Wigner transform of the quark exchange kernels are changed by only ∼20% under a large change in the relative [6] and [42] space symmetry of the antisymmetrized internal six-quark resonating group method wave function.
