Crysalis, Nuclei do produce electromagnetic radiation other than gamma rays, if properly excited. The kinds of excitation that occur in nuclear processes like fission and fusion involve large energies, so the radiation released is at very high frequencies, or gamma rays. However, the energy levels of nuclear states in magnetic fields of 1-10 Tesla are quite close, and the radiation in that case is in the radio frequency range. Nuclear magnetic resonance takes advantage of this fact to derive information about the magnetic environment of the nucleus which can then be used in a variety of ways. This technology is used in medical imaging, by the oil industry for examining oil-bearing strata, by material scientists to learn properties of materials, and by chemists to probe molecular structure. I'm not sure that I understand the second part of your question. Yes, there is less energetic movement that takes place in the nucleus other times than in nuclear processes, but this is not responsible for quantum mechanics. Quantum mechanics is the way matter interacts at the level of atoms. Just as there are certain rules about how objects like people, cars and planets move and interact, there are rules about how electrons, protons and neutrons move and interact. What is responsible for the relationship between Force and acceleration? It is the way the universe works.
