Repulsive short-range three-nucleon interaction
- Physics Department, New Mexico State University, Las Cruces, New Mexico 88033 (United States)
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 the trinucleons by about 200--300 keV. The contributions of intermediate {ital N}(1440) resonances (and the same meson exchanges) to this three-nucleon interaction are also estimated and shown to be small.
