One-meson-exchange Feynman diagrams are nonrelativistically reduced and unitarized via Schrödinger's equation. Properties of nucleon-nucleon scattering are calculated at incident laboratory energies of 25-310 MeV. Bound-state properties of the deuteron and of nuclear matter are also calculated. Mesons included are the $\pi$, $\eta$, $\sigma$, $\rho$, $\omega$, and $\varphi$. Very good over-all agreement with the experimental data is obtained. Important features of this "potential" include its momentum dependence, properly treated, and the contribution of the $\sigma$ "meson," which qualitatively changes the central/tensor force ratio from that of previous phenomenological potentials.
