Presented here are lifetimes, autoionization and radiative-decay rates of doubly-excited states of helium. Both calculated and experimental values are listed with notes on the methods used. The levels involved are designated in the notation of Sinanoglu and Herrick and in the hydrogenic style. Their energies, found by a number of experimenters and calculated by several theoreticians, are listed in a separate table. The literature has been covered from 1932 through 1976.
