† Recommended magnetic moments are for the bare nucleus with published results corrected consistently for diamagnetism (including error estimate).
  Where appropriate published results are also adjusted to the most recent adopted half-life for the state.
  Recommended quadrupole moments are adjusted using the best electric field gradient calculation for the system concerned.
  For details see the Reports referenced.

‡ In this listing published results are given without adjustment or correction.
