1. The problem statement, all variables and given/known data 1) Find the binding energy of N-13 nucleus, if the isotope of N-14 is more stable, what is the equation for the expected decay reaction. 2. Relevant equations E= mc^2 3. The attempt at a solution So I've figured out the binding energy, but I don't quite know what the problem is asking. Alpha, beta (both types), and gamma decay won't get N-13 to N-14.
