The Few Body Problem covers the proceedings of the Ninth International Conference on the Few Body Problem, held in Eugene, Oregon, USA on August 17-23, 1980. The book focuses on relativistic and particle physics, intermediate energy physics, nuclear, atomic, and molecular physics, and chemistry. The selection first offers information on nucleon-nucleon interaction in applications, including derivation of the nucleon-nucleon potential, nuclear many-body problem, and classic nuclear structure. The text also looks at three- and four-nucleon systems and graphs of three-body wave functions. The publication elaborates on K-meson experiments and non-mesonic few-nucleon phenomena. Topics include tests of invariance principles, properties of nuclei, dynamics, and hypernuclear physics. The manuscript also ponders on the Coulomb problem, atomic, molecular, and nuclear collisions, and muon capture in hydrogen isotopes. The selection is a dependable reference for readers interested in the few body problem.
