Appendix: Energy Levels of the Light Nuclei

The following isobaric level schemes of the light nuclei are presented here as a service to the reader of the preceding article. Coulomb-energy differences neutron-proton mass differences have been removed in accordance with the method described in (1, 2) in order to exhibit the correspondence of levels comprising isotopic-spin multiplets. Remaining mass differences are indicated in square brackets. Level energies in Mev, total angular momentum and parity J^π, and isobaric spin T are indicated. Uncertain values are enclosed in parentheses; uncertain, but probable, levels are shown by dashed . Further explanations are given in (3). Detailed references on which these compilations are based can be found in (4, 5). Atomic mass values have been taken from (6).
