1. The problem statement, all variables and given/known data Use the semi-empirical mass formula to show that when an even-even nucleus of large Z undergoes fission into two identical odd-even fragments energy will be liberated provided that the approximate condition: c1(A) + c2(Z²) + C3(A)^-5/12 > 0 is satisfied and give values for the constants c1, c2 and c3. 2. Relevant equations Semi-empirical mass formula 3. The attempt at a solution Do I use an example of any atom which is even-even and two other atoms which are odd-even. Then put it into the semi-empirical mass formula and then what exactly do I need?
