  1. c.e.: conversion electrons
  2. Energies in keV
  3. Intensities per `parent' decay of natural U (i.e. 0.956 238U, 0.044 235U)
  4. Data from compilations and amendments in Nuclear Data Sheets to Vol. 64 (1991)
    Levels marked `(fed)' receive no direct b-decay, but are fed by gs from higher levels
  5. g and conversion electron intensities are totals from given level; part may be associated with different (lower energy) primaries
