The disintegration energy for gamma decay of a nucleus is typically on the order of 10-100 keV and can even be on the order of MeV. Which of the following statements best describes why the energies are so much larger than from atoms?

a. Energy levels within the nucleus are spaced farther apart than atomic levels. b. The spins of the paired protons and neutrons within the nucleus are aligned within energy levels. c. The higher energies of the gamma rays are higher in probability of emission because they must tunnel through classically forbidden regions. d. All nuclei are only metastable, increasing binding energy exponentially when the nucleus is in an excited state. e. The Coulomb attraction within the nucleus places it lower in energy, therefore greater excitation energies are necessary.
