Title: Nuclear Reactions, Levels, and Spectra of Light Nuclei
Abstract: The study of the nuclear reactions of the light nuclei is not at present one of the basic investigations of nuclear physics. Already in 1935 attention was being concentrated on the simpler scattering problems, which would lead to some knowledge of the forces between nucleons. At present, emphasis is placed increasingly on attempts to interpret the inter-nucleon force in terms of a quantised field theory in which π-mesons are the quanta. The behaviour of the meson-nucleon system and the role played by new unstable particles in field theory have therefore become the central questions of nuclear physics. At first sight it might appear that the interactions of relatively complex systems of nucleons, I moving with non-relativistic velocities, could contribute little to an answer to these questions. This is however not so, at least in so far as the force between nucleons is concerned. Although important properties of this force can be inferred from the two-body system and from the knowledge that nuclear forces show saturation, some properties, such as charge independence, do seem to be best exhibited in the existence of nuclear charge multiplets. The existence of non-central couplings is perhaps basically a matter for high energy experiments, but such properties are also revealed in nuclear level splittings and in the sequence of single particle states of the nuclear shell model, and the possibility of many-body forces can only be investigated through a detailed knowledge of many-body systems.
