Question
Uranium-238 is the most commonly occurring isotope of uranium. i. A possible fission is given by the disintegration equation: 90 238 92 U→ 145La +3Br +3n. 57 Show that about 160 MeV of kinetic energy is released given the masses of 238.0508u, 144.9217u and 89.9306u for 238 U, 145 La and 90Br, respectively, the neutron mass of 939.6 MeV/c² and u =931.5 MeV/c2. ii. A second decay path is through alpha decay: 238 U → 234Th + a. 92 90 By comparing formulas, show that the Coulomb barrier for the fission process is over 8 times higher than that for the alpha pro- cess.
