Nuclear Data Sheets for A = 38

Nuclear spectroscopic information for the known nuclides of mass 38 (Mg,Al,Si,P,S,Cl,Ar,K,Ca,Sc,Ti) has been evaluated. The principal sources of the ‘adopted levels’ presented are Endt's evaluations (1990En08, 1978En02). The data sets for reactions and decays, including all available gamma-ray data, are based mostly on the original literature. There are no data available for the excited states in 38Mg, 38Al and 38P. Recent experiments have tried to identify 38Ti nuclide but no events have been associated with this nuclide with a half-life limit of <125 ns deduced from limit on experimental cross section. This nuclide is likely to be particle unstable. No experiments have yet been reported for the identification of the 38Sc nuclide which is also expected to be a prompt proton emitter.
