Properties of a Three-Nucleon Bound-State Wave Function

The bound state of the three-nucleon system is considered, using the Faddeev equations and an approximation scheme which involves the use of nonlocal separable potentials to describe the low-energy nucleon-nucleon interaction, and a phenomenological three-body force to represent the effects on the three-nucleon system of the nucleon-nucleon tensor and short-range interactions. The theoretical results for the dominant $S$ state are in reasonable agreement with the experimental data. An $S^{\prime }$-state probability of (1.9±1)% is predicted.
