Uranium-233 decays to thorium-229 by α decay, but the emissions have different energies and products: 83% emit an α particle with energy of 4.816 MeV and give 229Th in its groundstate; 15% emit an α particle of 4.773 MeV and give 229Th in ex-cited state I; and 2% emit a lower energy α particle and give 229Th in the higher excited state II. Excited state II emits a γ ray of 0.060 MeV to reach excited state I. (a) Find the γ ray energyand wavelength that would convert excited state I to the groundstate. (b) Find the energy of the α particle that would convert 233U to excited state II.
