WebApr 10, 2024 · Einstein, avec sa célèbre formule E=mc2, leur a donné la solution. Dans le processus, une petite quantité de masse a été perdue, qui a été convertie en énergie. C’était l’explication manquante d’un processus qui allait changer le monde : la fission nucléaire. WebThe ratios of excitation energy and binding energy are similar for the nuclei of U-233, Pu-239 and Pu-241. For U-238 and Th-232, on the other hand, the excitation energy required for fission is 6.5 MeV and thus much higher than the binding energy of the attached neutron of 4.8 MeV, so that fission of the nucleus is possible only if the neutron ...
