The Nubase2003 evaluation of nuclear and decay properties appeared in Nuclear Physics A, 2003, vol. 729, page 3-128 PDF
NUBASE contains experimentaly known nuclear properties, and some that have been estimated from extrapolation, for 3177 nuclides: mass, isomeric excitation energy, half-life, spin, parity, decay modes and intensities.
An electronic ASCII file of the NUBASE table,
for use with computer programs, is available from the
site of the AMDC.
