1 241 LNE – LNHB/CEA – Am de Radionucl ́eides Table 95 146 241 Am 95 146 Decay Scheme 1 Am- 241 decays 100% by alpha transitions to Np-237. Most of the decay (84.6 %) populate the excited level of Np-237 with energy of 59.54 keV. Branching of Am-241 decay by spontaneous fission is 3,6 (9) E-10 %. L’am ́ericium 241 se d ́esint`egre `a 100 % par ́emission alpha vers le neptunium 237. Le branchement principal (84,6 %) se fait vers le niveau excit ́e de 59 keV. Un faible branchement (3,6 (9) E-10 %) par fission spontan ́ee a ́et ́e observ ́e.
