• The Nambu-Salpeter-Bethe equation (so-called the Bethe-Salpeter equation) is solved numerically for the ^<1>S_0 state of nucleon-nucleon scattering. Three types of renormalizable meson-nucleon interactions-pion-, neutral-vector-meson- and scalar-meson-exchange-are assumed with ladder approximation. The negative-energy contributions are neglected. We have obtained a set of parameters (the exchanged meson masses and the mesonnucleon coupling constants) which reproduce the experimental values of the low energy scattering parameters (the scattering length and the effective range) and the solutions of the phase-shift analysis of energies 25~270 MeV. The vector-meson-nucleon coupling constant obtained by our calculation is smaller than that obtained by other formulations-the static coordinate space potential, 3-dimensional momentum-space representation and so on.
