The experimentally determined properties of A = 21-44 nuclides are complied and evaluated with special emphasis on nuclear spectroscopy. Separate tables for each of the nuclides reviewed present the available information about the following properties (in this order): - excitation energies Ex,- γ-ray branching ratios b( γ), - γ-ray mixing ratios σ, - lifetimes γm or widths Λ, - neutron, proton, or α-particle resonances, - partial widths, - single-nucleon transfer reactions, - beta-decay, - arguments for spin and parity ( Jπ) and isospin ( T) assignments. For each nuclide a master table summarizing the "best" or adopted values for Ex, Jπ; T and τm or Λ precedes the auxiliary tables listed above. The review of each A-chain concludes with a discussion of isospin multiplets. Figures are presented of the level schemes of all nuclei and, for each A-chain, an overview of the relative energies of the ground states and lowest analogue states of all nuclei in the chain.
