1. The problem statement, all variables and given/known data Could a 56Fe nucleus fission spontaneously into 2 28Al nuclei? Explain, your answer should include some calculations, should be based on the curve of binding energy. 2. Relevant equations B=(Zmh+Nmn-matom)*931.49 3. The attempt at a solution B=(26(1.00783u)+30(1.00866u)-55.9349u)*931.49=492.27MeV=>~8.8MeV per nucleon. from the curve of binding energy, 56Fe is the most stable atom, having the maximum amount of binding energy, thus it cannot fission spontaneously since it is bound too tightly.... i Have no idea if this is correct, but im sure it cant fission... ive looked on net and found heaps of reasons why it cant... but im really confused about how i am meant to answer the question.. can anyone help? thanks.
