Abstract

The three-nucleon interaction that is implied by the pion and the effective scalar and vector meson exchange components of the nucleon-nucleon interaction arises from the excitation of intermediate nucleon-antinucleon pairs. Using several wave-function models we show that this interaction is repulsive, reducing the calculated binding energy of thetrinucleons by about 200-300 keV. The contributions of intermediate N(1440) resonances (and the same meson exchanges) to this three-nucleoninteraction are also estimated and shown to be small.
