Homework Statement
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.
Homework Equations
B=(Zmh+Nmn-matom)*931.49
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 I am sure it can't fission... I've looked on net and found heaps of reasons why it cant... but I am really confused about how i am meant to answer the question.. can anyone help? thanks.
