We consider a model of nucleon-nucleon interactions in which the nucleon is a Skyrme soliton stabilized by ω-meson exchange, rather than the usual quartic Lagrangian term. Making the product approximation for the meson field matrix U and an additive approximation for the ω field, we obtain nonzero, central, spin-spin, and tensor NN potentials. Their magnitudes, but not shapes, are sensitive to the ω coupling constant. In general, the results are similar to others obtained, using the same kinds of approximations, with the usual Skyrme Lagrangian. Neither approach finds intermediate-range attraction in the I=0 central potential.
