The results from a potential model for the low-energy $\mathrm{NN}$ interaction based on Regge-pole theory are presented. The forces are due to the dominant parts of the $\pi$, $\eta$, ${\eta }^{\prime }$, $\rho$, $\omega$, $\phi$, $\delta$, $\epsilon$, $S^{*}$ trajectories in the complex $J$ plane, which are the well-known one-boson-exchange forces. Novel features are the dominant $J=0\mathrm{}$ parts of the Pomeron, $f$ $f^{\prime }$ and $A_2$ trajectories. At the Reggeon vertices we use exponential form factors, as suggested by high-energy fits. The Pomeron, $f$, and $f^{\prime }$ trajectories lead essentially to repulsive central Gaussian potentials. This soft-core, partially nonlocal potential model fits the $\mathrm{NN}$ data with $\frac{{\chi }^2}{\mathrm{data}}=2.09\mathrm{}$, which is lower than any other model we know of. The $\mathrm{NN}$ coupling constants have reasonable values, and the contributions of the Pomeron and tensor trajectories agree with estimates from high-energy fits.
