The present compilation includes experimental information on nuclear magnetic dipole and electric quadrupole moments found in print compilations (such as INDC(NDS)-0650, INDC(NDS)-0658 etc), the ENSDF nuclear database, peer-reviewed journals, international conferences and other resources. The online interface was created by Theo J. Mertzimekis under the IAEA auspices.

New: Recommended magnetic dipole moments for long-lived states (INDC(NDS)-0915 Rev. 2) and short-lived states (INDC(NDS)-0816), and recommended electric quadrupole moments (INDC(NDS)-0833) are available on the database. The recommended tables have been produced by N.J. Stone. Detailed discussion with Karel Jackowski (diamagnetism), Pekka Pyykko (electric field gradient computation data) and Andrew Stuchbery (transient field calibration) is gratefully acknowledged.
