Nuclear Data Sheets for A=38

All available experimental data of nuclear structure and decay are evaluated for the known nuclides of mass 38 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed results of this evaluation are presented with the best values recommended for level energies, half-lives, gamma-ray energies and intensities, decay properties (energies, intensities and placement of radiations), and other spectroscopic information. The Ar-38 nuclide remains as the most extensively studied via various reactions and decays; no excited states are known in Al-38 except for that an isomeric state is tentatively proposed from a recent beta-decay measurement (2015St14) the Sc-38 and except nuclides remain unidentified, with no experimental references reported for Sc-38 and with a measurement of fragmentation cross sections reported for Ti-38 but finding no evidence of its presence (1996B121, . This work supersedes the earlier full evaluation of A=38 by J.A. Cameron and B. Singh (2008Ca01).
