NUCLEON-NUCLEON SCATTERING FROM ONE-BOSON-EXCHANGE POTENTIALS .3. S WAVES INCLUDED

The nucleon-nucleon interaction is described over the laboratory scattering energy range 0-350 MeV by a potential used in conjunction with the Schrödinger equation. In momentum space the potential is a superposition of Born terms obtained from single exchanges of, 0, and 1 mesons, where the 0 and 1 are hypothetical scalar mesons with isotopic spin 0 and 1, respectively. Rather than taking the usual static limit, all terms of order p2M2 are retained. The inclusion of S waves requires the introduction of a cutoff factor. The meson coupling constants, the masses of the 0 and 1, and a cutoff parameter are adjusted to fit the experimentally determined phase parameters. A comparison with experimental phase-shift analysis shows a good qualitative fit, on the average. © 1969 The American Physical Society.
