The Nambu-Salpeter-Bethe eqation for the ^<1>S_0 state of nucleon-nucleon scattering is solved numerically including the negative-energy intermediate states. Calculation is made for the exchange of pion, isoscalar vector meson (μv=775.0 MeV) and scalar meson (μ_s=556.0 MeV), respectively. Our results show that the contribution from the negative-energy intermediate states does not alter the results from only positive-energy intermediate states for the vectormeson exchange, that it alters them quantitatively but not qualitatively for the scalar-meson exchange and that it alters qualitatively them for the pion exchange in the range of coupling constant q^2/4π-^^<15. Our results seem to show that the conjecture by Gammel et al., which connects the appearance of a pole in tan δ to Mandelstam's condition, is not valid.
