Abstract: (APS)
An approximate Bethe-Salpeter equation is used to calculate the N−N phase parameters. The one-boson-exchange (OBE) hypothesis is invoked to approximate the left-hand singularity. A good fit to the existing data is obtained, and certain phase parameters (D23, D21, and P23), which are not fitted well by existing OBE-potential (OBEP) models, are much improved. The observables are not fitted directly, but rather an approximate procedure suggested by MacGregor et al. is used to minimize the experimental χ2. Comparisons are made with the nonrelativistic OBEP used in conjunction with the Schrödinger equation.- nucleon nucleon: interaction
