Abstract

Alpha-particles are emitted in coincidence (i.e., within 5× $10^{- 6}$ sec.) with fission by $U^{235}$ and ${Pu}^{239}$ . The maximum range observed corresponds to an energy of 16 Mev. About one alpha per 250 fissions is emitted by ${U 1}^{235}$ and one alpha per 500 fissions by ${Pu}^{239}$ . The investigation is being continued.
