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 Americium (95 Am) is an artificial element, and thus a standard atomic weight cannot be given.

2021-04-09 · Americium-241 is an artificiallyproduced radioelement which has a half-life of 462 plus or minus 10 years and decays to Np/sup 237/ by alpha emission followed by low-energy gamma emission. The high specific activity of americium-241 (7.0 x 10/sup 9/ d/m/mg) combined with its reasonably long half-life makes it ideally sulted for the preparation of radioactive sources.
