Refer to Illustration 7.15, the energy released by the alpha decay of 232 U 92 is found to be 4.3 MeV. Since this energy is carried away as kinetic energy of the recoiling 234 Th 90 nucleus and the alpha particle, it follows that KE th + KE alpha = 4.3 MeV. However, KE th and KE alpha are not equal. Which
