The range of applications of the knowledge gained from experiment and from the theory of the two- and three-nucleon systems is equivalent to all of nuclear physics in the energy range below the pion and hyperon thresholds. At present, it is difficult to separate the uncertainties in the two-body interaction as they affect the three-body system from the contribution of the three-body interaction. An essential complication arises in the three-body system from the undoubted presence of three-body interactions. The three-nucleon system gives necessary information concerning this problem. However, this analysis leaves certain ambiguities in the interaction, particularly in the off-energy shell behavior. It can be determined from nucleon–nucleon scattering and from the nucleon–nucleon ground state. The study of few nucleon systems has as a principle objective the determination of the nuclear forces. This chapter reviews the nuclear Thomas–Fermi model and some of its applications of astrophysical interest. Brueckner, Robert Buchler, in Few Particle Problems, 1972 Publisher Summary
