摘要: Abstract The experimental nuclear structure data and decay are evaluated for the known nuclides of mass 40 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed information is presented with best values recommended level energies, half-lives, γ -ray energies intensities, properties (energies, intensities placement radiations), other spectroscopic data. Ca K remain as most extensively studied from many different reactions decays; no excited states in Mg, P Ti. This work supersedes earlier full evaluation A=40 by J. Cameron B. Singh (2004Ca38).
